If a service fee seems wrong, identify the payment method before deciding what to do. A charge is easier to challenge when it differs from the price shown at checkout, the contract, or the invoice; was billed twice; or covers a service you never received. A disclosed fee for a service that was delivered may be a customer-service or contract dispute rather than a credit-card billing error.

For a qualifying U.S. credit-card billing error, written notice must reach the card issuer within 60 days after the first statement containing the error was sent. That deadline doesn't automatically apply to debit cards, bank-account fees, ACH payments, marketplace refunds, or contractor invoices.

Identify the payment method first

Calling a charge a "service fee" doesn't establish that it's valid or invalid. Compare the amount with the price shown before checkout, the contract, the invoice, and the statement.

Protect the U.S. credit-card deadline

The Fair Credit Billing Act provides a process for certain consumer credit-card billing errors. The Federal Trade Commission's credit-card guidance explains the process.

Possible billing-error issues can include a wrong amount, a duplicate charge, or a charge for a service that wasn't accepted or delivered. A plainly disclosed fee for a service you received may not qualify simply because you now think it was too high.

For a covered error:

1. Write to the issuer at the billing-dispute or billing-inquiries address shown on the statement. That address may differ from the address used for payments.
2. Make sure the letter reaches the issuer within 60 days after the first statement containing the error was sent.
3. Identify your name, account, transaction date, amount, and reason for the dispute. Include copies of relevant records.
4. Keep a copy of the letter, attachments, and proof of delivery.

The issuer generally must acknowledge the complaint in writing within 30 days unless it has already resolved the issue. It must resolve the dispute within two complete billing cycles, and no later than 90 days after receiving the letter.

For a covered billing error, you generally don't have to pay the disputed amount or related finance and other charges while the issuer investigates. You still need to pay the rest of the bill on time. Don't stop paying the entire credit-card balance because one fee is under review.

The 60-day rule protects a dispute procedure; it doesn't guarantee a refund. The issuer may decide that no billing error occurred if the fee was clearly disclosed, correctly calculated, and charged for a service that was provided.

If you've moved, one additional condition may matter. The FTC says you must have given the issuer your new address in writing at least 20 days before the end of the billing period to use these protections. Follow the address and delivery instructions on the statement.

What the 60-day rule doesn't control

The federal credit-card billing-error process doesn't automatically govern:

• An ordinary checking-account maintenance fee
• A debit-card transaction
• An ACH payment or other electronic transfer
• A wire transfer
• A platform's voluntary refund policy
• A contractor's invoice or a lawyer's bill

Use the applicable bank, provider, contract, or state-law process for those disputes. A customer-service call, an in-app complaint, or a request for a chargeback may not preserve the credit-card written-notice deadline.

Gather evidence and calculate the amount

A short, organized record is more useful than a long explanation. Collect:

• The statement showing the merchant name, date, and amount
• The receipt, order confirmation, or checkout fee breakdown
• The advertisement, price page, listing, or terms shown when you agreed
• The contract, signed estimate, fee agreement, change order, or cancellation policy
• An itemized invoice and your calculation of the disputed amount
• Emails, platform messages, call notes, and case numbers
• Photos or videos showing a service problem, with the date recorded separately
• Proof of cancellation, return, non-delivery, or a promised credit
• Any partial refund or credit already issued

Create a one-page timeline with the dates, people contacted, promises made, and amount still in dispute. Mark each attachment with a short description. Send copies rather than originals, and remove unnecessary account numbers and other sensitive information.

Ask the provider to correct the fee

A written request gives the merchant or service provider a chance to fix the problem and creates a record. Keep it factual:

1. Identify the transaction and exact fee.
2. Explain why the amount is wrong.
3. Point to the contract, listing, receipt, or message that supports your position.
4. Request a specific remedy, such as a full refund, partial refund, corrected invoice, or removal of a duplicate charge.
5. Set a reasonable response date, such as 10 business days, unless the agreement or law provides another period.
6. Ask for an itemized explanation if the provider disagrees.

You can ask for a goodwill refund when the fee was disclosed but the experience was poor. That is different from reporting an unauthorized charge or preserving a legal billing-error claim. If a credit-card deadline is approaching, send the issuer's written notice while the merchant reviews your complaint.

When a provider offers a partial refund, confirm the amount, payment method, and expected date in writing. Update your dispute so you seek only the remaining balance.

Send a separate notice to the credit-card issuer

A merchant's refusal doesn't end the matter, and a merchant's internal deadline doesn't replace the issuer's process. If the charge may qualify as a credit-card billing error, address the letter to the issuer's billing-inquiries address and explain the facts plainly.

Follow the issuer's delivery instructions. Keep the letter, attachments, delivery record, and any acknowledgment. If you also submit an online dispute, save the confirmation screen and case number. A written notice sent to the specified billing address is the safer way to use the federal billing-error process.

Handle common types of service-fee disputes

Banks and checking accounts

A bank-account service fee isn't the same as a credit-card billing error. Review the deposit agreement and current fee schedule. Check whether the fee was disclosed, whether a waiver or minimum-balance condition applied, and whether the bank charged it more than once.

Ask the bank in writing to reverse an incorrect fee. If it says the fee is valid, request the specific agreement or fee schedule it relied on. When the issue involves an electronic transfer or unauthorized transaction, describe exactly what happened and ask for the required notice method and deadline.

Booking sites and marketplaces

A platform's refund process is separate from the payment provider's dispute process. Report the problem promptly through the platform's current support or resolution channel. Save:

• The original listing and fee breakdown
• Reservation or order details
• Photos and videos of the condition or delivery problem
• Messages with the host, seller, or provider
• The platform case number and every response

Read the terms that applied to the reservation or order. Reporting periods and refund conditions can vary by platform, product, and account.

If you paid by credit card, a platform complaint doesn't prevent you from considering a separate issuer dispute. The issuer will still decide whether the facts fit a covered billing error. A disclosed fee for a service that was delivered may be difficult to challenge solely because the fee now seems excessive.

Contractors and home-service providers

Compare the final invoice with the signed scope, price, allowances, hourly rates, materials, and approved change orders. Ask the contractor to identify every amount that wasn't in the original agreement.

A document labeled an "estimate" isn't always decisive. As Nolo's contractor overcharge guide notes, the substance of the written agreement and applicable state law can matter. Rules differ, so don't assume an estimate permits unlimited increases or that you can withhold every payment.

If the work is defective or incomplete, document the condition before repairs or replacement work begins unless there is an urgent safety issue. Give the provider a reasonable chance to inspect or correct the problem while preserving evidence and following the contract.

Lawyers and other professionals

Start with the signed fee agreement, engagement letter, billing policy, and itemized invoice. Highlight entries that appear duplicated, outside the agreed scope, incorrectly calculated, or inconsistent with the billing arrangement.

Ask for a written explanation and a corrected bill. If direct discussions fail, check whether your state bar or professional regulator offers fee mediation or arbitration. An arbitration clause in the agreement may also affect where the dispute can be filed.

Escalate when the first request fails

Move to the next channel with the same organized record:

1. Request a higher-level review. Send a short follow-up with the original request, evidence index, and response you received.
2. Use the payment-provider process. For a credit card, confirm that the issuer received the written billing-error notice and ask how to submit more evidence or request reconsideration.
3. Contact the appropriate regulator. Depending on the provider and issue, that may be a state attorney general, licensing board, financial regulator, public utility commission, or professional regulator.
4. Review alternative-dispute-resolution terms. An arbitration or mediation clause can affect the next step. Check filing costs, location, deadlines, and whether the decision is binding.
5. Consider small claims court or another legal remedy. Filing limits, notice requirements, court costs, limitation periods, and contract terms vary by state. Check them before filing.

A regulator complaint may encourage a response, but it doesn't guarantee a refund. Arbitration and court proceedings aren't automatic wins either. The strongest escalation packet shows the agreement, promised price, disputed charge, calculation, request, and provider response.

Mistakes that weaken a service-fee dispute

• Waiting for a merchant response until a payment-method deadline passes
• Treating the credit-card 60-day rule as a universal deadline
• Calling an authorized charge "fraud" because you regret the purchase
• Sending only a bank statement without showing why the amount is wrong
• Ignoring the contract's change-order or cancellation procedure
• Demanding a full refund when part of the service was properly delivered
• Stopping payment on an entire credit-card bill instead of paying undisputed amounts
• Relying on a phone promise without requesting written confirmation
• Posting accusations publicly instead of preserving a private, factual record
• Filing in court or arbitration without checking the agreement and applicable deadline

Quick answers

Can I dispute a service fee I agreed to?

You can ask for a refund or correction, but agreeing to a fee can make the dispute weaker. Focus on a mismatch between the amount charged and the disclosed terms, a duplicate charge, a service that wasn't delivered, or another specific error.

Does the credit-card 60-day deadline apply to debit cards?

Not automatically. The federal credit-card billing-error procedure is different from procedures for debit, prepaid, checking-account, ACH, and other transactions. Contact the bank or provider promptly and ask for the correct written process.

Should I contact the merchant or my card issuer first?

Contact the merchant when practical, but protect the issuer deadline at the same time. A merchant's investigation doesn't extend the time for written credit-card billing-error notice.

What should I do if the charge was unauthorized?

Contact the card issuer or bank immediately through an official phone number or secure account channel. State that you don't recognize or authorize the transaction, secure the account as directed, and keep the report number. Don't treat a suspected unauthorized charge as an ordinary negotiation.

This is general information for U.S. consumers, not legal advice. Your contract, payment method, state law, and the provider's current terms may change the available remedy. First identify the payment rail, calculate the disputed amount, and send a dated written request before any applicable deadline.
