A merchant won't refund you, a charge that shouldn't be there, or a collector chasing a debt? Dispute it formally.
AI drafts the letter that fits your situation — a contract-based refund demand to a merchant that won't honor its own cancellation policy, a Fair Credit Billing Act dispute to your card issuer for a charge you never made, or a Fair Debt Collection Practices Act letter to a collection agency.

What's actually happening.
You cancelled a trip, subscription, or ticket inside the merchant's own stated cancellation window — and they kept your money anyway. Or a charge shows up on your card statement that you never made. Both are billing disputes, but they don't always land on the same desk. An unauthorized charge on a credit card always goes to your card issuer as a Fair Credit Billing Act billing-error notice — a formal dispute process with real deadlines on the issuer's side, where your notice reaches them within the 60-day window. A refused refund goes there too, and it's the stronger route, when you paid by credit card, already asked the merchant, and gave us the statement date confirming that window is still open. Otherwise, it's a breach of the cancellation or refund policy you agreed to when you paid, and the letter demands the money back from the merchant directly, on that basis. And a third situation lands on this same form: a collection agency pursuing you for a debt. That one isn't a charge dispute at all — you bought nothing from a collector, so there's no refund to demand and no billing error for an issuer to investigate. It runs on the Fair Debt Collection Practices Act instead, and you tell us what the letter should do: make them verify the debt, tell them to stop contacting you, dispute it outright, or put a settlement offer on the table.
What we draft.
I am writing to demand a refund of $1,240.00, charged to my credit card on April 2, 2026, for a four-night stay at [RESORT NAME], reservation #[CONFIRMATION NUMBER]. At the time of booking, the cancellation policy stated a full refund for cancellations made at least 14 days before check-in. I cancelled this reservation on May 1, 2026 — 17 days before the May 18 check-in date, inside the window the policy set. Your confirmation and the cancellation policy in force at the time of purchase together form our agreement, and I met its terms in full. Despite this, I was informed on May 3, 2026 that no refund would be issued. This refuses a refund I am owed under the plain terms of the policy I relied on when I booked. I am demanding a refund of the full $1,240.00 to the original payment method, within 14 days of the date of this letter...
Full letter includes: what was purchased and when, the merchant's own cancellation or refund policy quoted or closely paraphrased, your cancellation date checked against the policy's own deadline — asserted plainly when it was timely, argued from other grounds (a misrepresented policy, a refund promised and not honored) when it wasn't — a one-time refund demand with a 14-day deadline, your state's consumer protection statute cited by name where our verified table covers it, and an escalation notice — a state attorney general complaint and small claims court. Where the charge was one you never authorized on a credit card — or you paid by credit card, already asked the merchant, and gave us the statement date confirming your issuer's 60-day FCBA window is still open, the stronger route — FightThis drafts a different letter instead: a formal billing-error notice to your card issuer's billing-inquiries department under the Fair Credit Billing Act, 15 U.S.C. § 1666. And where the other side is a collection agency rather than a merchant or an issuer, the letter is different again: a Fair Debt Collection Practices Act letter addressed to the collector, built around the one thing you asked it to do — verification, cease contact, dispute, or a settlement offer you named the figure for — and closing with language stating it is not an acknowledgment of the debt or an admission that it is valid.

Laws we cite.
We ground every letter in real statutes and regulations. Here's what applies to your situation:
15 U.S.C. § 1666 Fair Credit Billing Act — your right to dispute a billing error directly with your card issuer within 60 days of the statement. Covers a charge you didn't authorize, and also covers a merchant refusing a refund you've already asked them for, when you paid by credit card and gave us the statement date confirming your 60-day window is still open — a stronger route than a merchant demand alone.
Regulation Z The implementing regulation for the FCBA's billing-error procedures — the framework your issuer must follow when you dispute in writing.
FCBA timelines Where your letter goes to your card issuer and reaches them inside the 60-day window: they must acknowledge your dispute within 30 days and resolve it within two billing cycles, and you may withhold payment on the disputed amount while it's under investigation. Past that window, we still draft the letter, but as a request under the issuer's own billing policy rather than a statutory demand.
State consumer protection law Where your letter goes to a merchant: it cites your state's consumer protection or deceptive trade practices act by name, drawn from a verified table covering 45 of the 51 U.S. jurisdictions. Where your state isn't in the table, the letter argues from contract alone with no statute named.
Contract & cancellation policy The merchant's own booking confirmation and stated cancellation or refund policy are the agreement between you and the merchant — refusing a refund for a cancellation made inside that window breaches those terms, independent of any statute.
15 U.S.C. § 1692g Fair Debt Collection Practices Act — where a collection agency is pursuing you: a dispute made in writing within 30 days of your receiving the collector's validation notice requires it to stop collecting until it mails you verification of the debt or a copy of a judgment. Tell us the date that notice arrived and the letter asserts that duty; without that date we request verification without claiming a deadline we can't document.
15 U.S.C. §§ 1692c–1692f The FDCPA's rules on collector conduct — communication at inconvenient hours or at your workplace, harassment, false or misleading representations, and unfair practices. Where you describe specific incidents, the letter sets each one out and names the provision it appears to violate. The CFPB's Regulation F, 12 C.F.R. part 1006, is cited alongside it.
15 U.S.C. § 1692e(8) Once a collector is told a debt is disputed, it may not report credit information about it without reporting that it is disputed. This one carries no deadline, so it is the ground the letter relies on when the 30-day validation window has passed or can't be dated.
Who this isn't for.
We're honest about our limits. FightThis may not be right if:
- The charge you didn't authorize was made on a debit card, bank transfer, or a payment app like PayPal, Venmo, or Cash App — those don't go through the Fair Credit Billing Act. Contact your bank's fraud line directly; it's faster and it's the right process. If you paid by check or wire, there's no card-network or bank dispute process for an unauthorized charge either — talk to your bank about what, if anything, can still be recalled or reversed.
- You want out of a timeshare contract generally — we dispute one specific timeshare charge (a rescission-period claim, a disputed maintenance fee or assessment, or a cancelled stay), never a full exit or cancellation of the ownership agreement.
- You're in active litigation over this charge or debt — the merchant or issuer has sued you, or a collector has filed suit. A letter is not a defence to a lawsuit; you need an attorney for that.
- The problem is on your credit report rather than your card or merchant statement — that's a credit bureau dispute, which we also support.
- The account a collector is chasing is a business debt rather than a personal one — the Fair Debt Collection Practices Act protects consumers, and a letter built on it doesn't fit a commercial account.
- You want a collector to delete accurate information from your credit report in exchange for payment — we won't draft that. A settlement letter asks the collector to report the account consistently with the resolution; it never trades payment for deleting something true.
If your situation is high-stakes, please find a local attorney. Many state bars have free or low-cost referral services.
Common questions.
Who does my letter go to, and how is that decided?
You make one choice, and the facts decide the rest. First you tell us whether you're disputing a charge on your card or account, or a debt a collection agency is pursuing you for — we don't guess at that, because only you know it, and the form has no default. Pick the collector and the letter goes to the collection agency under the Fair Debt Collection Practices Act, and nowhere else. Pick a charge and the facts take over from there. A charge you never authorized on a credit card always gets a Fair Credit Billing Act billing-error notice to your card issuer's billing-inquiries department. So does a refused refund, if you paid by credit card, already asked the merchant, and gave us the statement date confirming your issuer's 60-day window is still open — that route has statutory teeth a merchant demand doesn't, so it's the stronger play. Otherwise — you haven't asked the merchant yet, the window has closed, you didn't give us a statement date so we can't confirm it's open, or you paid another way — we draft a contract-based refund demand addressed to the merchant instead, citing its own cancellation or refund policy and, where available, your state's consumer protection law.
What if I paid by debit card, bank transfer, an app like PayPal, Venmo, or Cash App, or by check or wire?
For a charge you didn't authorize, we can't help with any of those — only an unauthorized charge on a credit card gets an FCBA letter. Contact your bank directly; for debit, bank transfer, or a payment app that's their fraud or electronic-transfer dispute process, and it can often reverse the charge faster than any letter. If instead a merchant is refusing a refund you're owed under its own policy, we can still draft that demand regardless of how you paid.
Can you get me out of my timeshare?
No. We draft letters for one specific disputed timeshare charge — a rescission-period claim, a disputed maintenance fee or special assessment, or a refund for a cancelled stay. We do not draft timeshare exit or contract-cancellation letters, full stop. That segment is where consumers are most reliably fleeced by services that promise to get you out and either don't deliver or damage your position further. If your goal is exiting the contract generally, this isn't the right tool.
How long do I have to dispute an unauthorized charge with my card issuer?
Your notice must reach your issuer within 60 days of the statement that first showed the error. If you're demanding a refund from a merchant instead, there's no FCBA deadline — our letter sets its own firm 14-day deadline for the merchant to respond.
Do I have to keep paying the disputed charge?
When your letter goes to your card issuer and reaches them within the FCBA's 60-day window, you may withhold payment on the disputed amount while it's under investigation — you still owe the rest of your balance as usual. Past that window, the letter can still go to your issuer where that applies, but as a request rather than a statutory right to withhold payment. A merchant refund demand never carries that right; it simply demands the money back.
What counts as an FCBA billing error?
A charge you didn't authorize, a charge for the wrong amount, duplicate billing, goods or services you never received, or goods or services that weren't as described or were defective.
What if the product arrived but wasn't as promised?
That's a claims-and-defenses situation under the FCBA — you should first attempt to resolve it with the merchant. Our letter classifies your dispute and notes that step where it applies.
How fast does my card issuer have to respond?
Under the FCBA, when your notice reaches your issuer within the 60-day window, it must acknowledge your dispute within 30 days and resolve it within two billing cycles, and confirm the outcome in writing. Outside that window, we still draft a letter to the issuer where that's the right recipient, but it asks rather than invokes those statutory deadlines.
What can a letter to a debt collector actually ask for?
One of four things, and you pick which — the letter does exactly the one you chose and never blends two. A validation demand asks the collector to verify the debt and name the original creditor. A cease-communication notice states in writing that you refuse to pay or want contact to stop, which is what invokes 15 U.S.C. § 1692c(c). A dispute states the basis you actually gave — not yours, already paid, wrong amount, identity theft, wrong person — and demands verification. A settlement offer puts forward a figure you supplied, expressly without admitting the debt is valid, and asks for written confirmation before you pay anything.
Will a letter make the debt go away, or get it off my credit report?
No, and we won't write a letter that says it will. Disputing a debt doesn't erase it, doesn't remove it from your credit report, and doesn't stop a collector from suing. What it does do is force the account onto the record: once you've disputed it, the collector can't report credit information about it without also reporting that it's disputed, and inside the validation window it has to stop collecting until it sends you verification.
What if the debt is old enough to be past the statute of limitations?
We won't state that it is. Whether a debt is time-barred turns on your state, the kind of debt, and dates you may not have — and in some states a payment or a written acknowledgment restarts the clock, which is exactly why a careless letter can make things worse. Where the age of the account suggests the question is live, the letter says you believe the debt may fall outside the applicable limitations period and asks the collector to state the date of first delinquency. It names no state statute, and it concedes nothing.
Can I sue a collector that breaks the rules?
The FDCPA gives you a private right of action: actual damages, such additional damages as the court may allow up to $1,000 in an individual action, and costs and a reasonable attorney's fee if you win — with a one-year deadline from the violation. That $1,000 is a ceiling the court may allow in the case, not an amount per violation, and our letters never claim otherwise or name a total you intend to recover. If the conduct has been serious, talk to a consumer attorney.
We mail it for you
Whichever letter fits your situation, certified mail gives you dated proof it arrived. A dispute to your card issuer runs on the FCBA's 60-day window from your statement date; a demand to a merchant sets its own 14-day deadline in the letter itself; a dispute to a collector turns on a 30-day window running from the validation notice they sent you. In every one of them, you want proof of when it landed.
