Short answer: Start with the business that charged the fee. Give the booking or account number, the exact amount, your cancellation date and time with the time zone, the policy language you relied on, and the reason the charge appears wrong. Attach the relevant proof and ask for a specific remedy, such as a refund, credit, or removal of the fee.

If the charge is on a U.S. credit card and the facts support a qualifying billing-error claim, send a separate written dispute to the card issuer. The issuer must receive it within 60 days after the first statement containing the error was sent. That deadline applies to the federal credit-card billing-error process, not to every request that a merchant waive a cancellation fee. A card dispute also isn't an automatic refund.

Start with the type of problem

A cancellation fee isn't automatically wrong because it seems expensive. Your position is stronger when the business used the wrong policy, ignored a timely cancellation, charged a different amount from the one disclosed, continued billing after cancellation, or charged for a service that wasn't delivered.

What controls the result?

The terms in effect when you booked

Look at the version of the booking, membership, lease, or service terms that you accepted. Check for:

• The free-cancellation or notice period
• The time zone used for the deadline
• No-show and late-cancellation rules
• A nonrefundable price option
• Automatic-renewal and free-trial terms
• The required cancellation method
• Exceptions for provider cancellations, service failures, or documented emergencies

Save the confirmation and policy page from the time of purchase. A current policy page may not be the version attached to your transaction.

State laws can add protections for particular industries or transactions, but there's no single U.S. rule that cancels every cancellation fee. Don't call a fee illegal unless you've identified a rule that applies to your state and situation.

The payment method

A complaint to the business and a credit-card billing dispute are separate processes.

For a U.S. credit card, the FTC's guidance on disputing credit-card charges says to send written notice so the issuer receives it within 60 days after the first bill with the error was sent. Identify the account, amount, date, and reason for the dispute, and include copies of your evidence. Use the billing-inquiries address on the statement, which may be different from the ordinary customer-service address.

For a qualifying written notice, the issuer generally must acknowledge the complaint within 30 days and resolve it within two billing cycles, and no later than 90 days. Keep paying the undisputed part of the bill on time and follow the issuer's instructions.

A cancellation-fee disagreement isn't automatically a billing error. The credit-card process is more likely to fit when the charge was unauthorized, the amount was wrong or duplicated, the service wasn't provided as agreed, or the records show a charge after a valid cancellation. State the facts rather than labeling the dispute "fraud."

These federal credit-card procedures don't apply in the same way to debit cards, prepaid cards, or bank-account payments. Contact the bank or payment provider promptly and ask which error or unauthorized-payment process applies.

Recurring subscriptions

A renewal may be worth challenging if you canceled before the renewal date, never agreed to recurring billing, or were charged contrary to the terms shown at sign-up. Keep the sign-up page, renewal notice, cancellation confirmation, and account history.

The FTC announced a final click-to-cancel rule in 2024. The announcement by itself doesn't decide whether a particular past charge must be refunded. Before claiming that a subscription violated a specific rule, check the current terms and current agency information. The FTC announcement provides background.

Airbnb and similar platforms

The platform's reservation policy usually matters more than a general hotel rule. Airbnb's official cancellation-policy page says its standard cancellation policies include a 24-hour cancellation period. A nonrefundable option and long-term stays can have different terms; Airbnb says its long-term policy applies to reservations of 28 or more consecutive nights.

Check the policy attached to the specific reservation. If the host canceled, the accommodation had a serious problem, or another exception may apply, use Airbnb's support or resolution process and provide evidence. Don't assume every reservation qualifies for a full refund.

Put these facts in the first email

A useful complaint usually fits on one screen. Include:

1. The transaction or account number
2. The amount and date of the disputed charge
3. When and how you canceled, including the time zone
4. The policy wording that supports your position
5. The correction you want
6. A request for the clause and calculation if the business disagrees

Use "I dispute" for a factual or billing error. If the fee appears to follow the policy and you're asking for compassion, say "I request a one-time waiver" instead. Don't use both arguments unless both are accurate.

18. Written credit-card billing-error notice

Use this only when the facts support a qualifying credit-card billing error. Send it to the billing-inquiries address on the statement. The issuer's secure dispute channel may also accept written notices, but follow the issuer's instructions. The FTC sample dispute letter shows the basic format.

Subject: Written billing-error dispute for account ending [last four digits]

Dear Billing Inquiries Department,

I am disputing a [$XX.XX] charge posted to my credit-card account on [date] by [merchant]. The account ends in [last four digits].

This charge is a billing error because [the charge was not authorized, the amount is wrong, the service was not provided as agreed, or another specific factual reason].

Please investigate and correct the account. Enclosed are copies of [statement page, confirmation, cancellation record, policy, and correspondence]. Please confirm receipt and send the result of your investigation in writing.

Sincerely,
[Full name]
[Billing address]
[Phone number]
[Account information requested by issuer]

Don't describe a charge as unauthorized unless you genuinely didn't authorize it. A merchant's refusal to waive a clearly disclosed fee isn't automatically fraud.

Evidence to attach

Send copies, not irreplaceable originals. Depending on the dispute, include:

• The booking, membership, or subscription confirmation
• The cancellation policy shown at checkout
• The contract or account terms in effect at the time
• A cancellation email, receipt, ticket, or confirmation number
• Screenshots showing the date, time, time zone, and account status
• The invoice or statement showing the fee
• Messages with the merchant, host, airline, or platform
• Proof of a provider cancellation, service failure, or material change
• Documents supporting a requested goodwill exception
• A short timeline of what happened

Redact unnecessary personal information. Never include a full card number, password, Social Security number, or identity document unless the recipient's secure system specifically requests it.

How to send and track the dispute

1. Use the official merchant channel. Send the email through the listed support address or account portal. For a platform booking, open a support or resolution case as well when appropriate.
2. Send the card notice separately. Use the billing-dispute address printed on the credit-card statement. A call or chat can create a useful record, but don't rely on it alone when written notice is required.
3. Ask for one clear remedy. Lead with a refund, credit, fee removal, or waiver. If you'd accept alternatives, list them in order.
4. Choose a practical reply date. Five to seven business days is a reasonable request for a response, not a universal legal deadline.
5. Keep the paper trail. Save the sent email, attachments, delivery confirmation, automated replies, case number, and response together.
6. Watch the card deadline. If the facts may support a billing-error dispute, send the issuer's written notice before the 60-day period expires. Don't wait for the merchant if the deadline is close.

Certified mail can help prove that a written notice was delivered when a contract or applicable rule requires it. It doesn't prove the fee was wrong. "Certified email" also has no universal legal status, so use the notice method specified in the agreement or on the card statement.

If the merchant denies the request

Ask for these details in writing:

• The exact policy clause
• The policy version or terms attached to your transaction
• The calculation showing how the fee was determined

If the response confirms that the fee was clearly disclosed and correctly applied, a goodwill request may work better than a legal threat. If it shows a wrong date, wrong amount, missing cancellation, or charge after cancellation, reply with the record that contradicts it.

For a credit-card charge, submit the response and your evidence through the issuer's dispute process. A chargeback is an investigation, not an automatic refund. The issuer can deny the dispute if the evidence shows that the fee was authorized and correctly assessed.

For a debit card, prepaid card, or bank-account payment, contact the financial institution promptly and ask for its dispute or unauthorized-payment procedure. Don't assume the credit-card 60-day rule applies.

For a platform, continue through its internal appeal or resolution process. For a utility, airline, landlord, or other regulated service, identify the state or industry regulator that handles that type of complaint. An external complaint can document the problem, but it doesn't guarantee a refund for a properly disclosed fee.

Common mistakes

• Treating the 60-day credit-card deadline as a deadline for every merchant complaint or payment type
• Sending the dispute only to a general customer-service inbox
• Calling a policy disagreement "fraud"
• Threatening a chargeback before explaining the records and policy
• Relying on a current policy page instead of the terms accepted at purchase
• Leaving out the cancellation time zone
• Telling a long emotional story without stating the remedy
• Including excessive personal or card information
• Disputing an amount after the merchant has already refunded it
• Waiting for the merchant's answer until an issuer deadline has passed

Frequently asked questions

Is every cancellation fee illegal?

No. A fee may be enforceable if it was clearly disclosed and applied according to the agreement. Your case is stronger when the fee was hidden, misapplied, charged after cancellation, or connected to a service the business didn't provide.

Does the FTC give me 60 days to dispute any cancellation fee?

No. The 60-day period applies to written disputes of qualifying credit-card billing errors under the federal process. It isn't a universal deadline for a merchant complaint, debit-card dispute, or every chargeback reason.

Should I contact the business before my card issuer?

Usually, yes. The business may be able to correct a simple timestamp or billing mistake quickly. Don't delay the issuer notice if the credit-card deadline is approaching or the charge may fit a billing-error category.

Can a nonrefundable booking still be disputed?

Yes, but "nonrefundable" may describe the normal policy. It doesn't answer whether the business used the correct terms, charged the correct amount, honored a provider cancellation, or continued billing after a valid cancellation. It does make a goodwill request more realistic than an automatic-refund claim.

Can I use one email for Airbnb, a hotel, and a subscription?

You can use the same basic structure, but quote the policy and cancellation method for the specific transaction. Airbnb reservations, hotel bookings, subscriptions, and memberships often use different terms.

Does certified mail guarantee success?

No. It can help show when a notice was sent and delivered, but the policy and evidence still determine whether the fee should be reversed.

What if I never receive a response?

Send one concise follow-up using the original reference number. Then consider the payment provider's dispute process, the platform's escalation route, or the appropriate regulator if the facts support escalation. Keep a copy of every step.
