If a service fee looks wrong, compare it with the invoice, agreement, order confirmation, pricing information, and any cancellation record. Then send the provider a short written complaint that identifies the exact charge, explains the problem, and requests a specific remedy.

If you paid by credit card and the issue may be an eligible billing error, send a separate written notice to the card issuer. For that process, the FTC says the notice must reach the issuer within 60 days after the first bill containing the error was sent. A complaint to the provider alone may not preserve that deadline. If the transaction is genuinely unauthorized, contact the bank or card issuer promptly.

These templates are for U.S. consumers. Replace the bracketed text, remove anything that does not apply, and save copies of everything you send.

What to include in a service fee complaint email

A useful complaint should identify:

Don't include your full card number, password, security code, or identity documents unless the provider specifically requests them through a secure channel.

First identify the type of dispute

The next step depends partly on the problem and the payment method:

Problem First contact Key limitation
Incorrect provider invoice Provider's billing or support team Use the invoice, order, agreement, and provider policy to support the correction; applicable law may also matter
Subscription renewal or cancellation issue Provider's cancellation or billing team Removing an app may not cancel an account; follow the stated cancellation process and save the confirmation
Eligible credit card billing error Provider and credit card issuer A provider message does not replace the issuer's separate written dispute process
Debit card, ACH, prepaid, or payment-app charge Provider and the relevant bank or payment service The credit-card 60-day process does not automatically apply to other payment methods
Truly unauthorized transaction Bank or card issuer promptly An unfamiliar charge may be an unfamiliar merchant descriptor or an authorized transaction; check the account history first

For a service you knowingly authorized but that was billed at the wrong rate, describe it as an incorrect charge or overcharge rather than calling it fraud.

Subject: Dispute of Charge After Cancellation - Account [ID]

Dear [Customer Support or Billing Team],

I canceled [service or subscription] on [date] through [website, email, phone, or other method]. My cancellation confirmation or case number is [confirmation number].

Despite that cancellation, I was charged [amount] on [date] for [service or renewal]. Please review the cancellation record, reverse this charge, and confirm that the subscription is closed with no further recurring billing.

Use this when a recurring fee increased and you need an explanation or correction under the agreement.

Subject: Request to Review Subscription Price Increase - Account [ID]

Please reply by [date].

Subject: Refund Request for Service Not Delivered - Order [number]

Use this when software service failed to meet a service-level commitment that includes a credit or another remedy.

Subject: Request for Contractual Service Credit - Account [ID]

Dear [SaaS Support or Account Team],

I am requesting a review of the service credit for the outage on [date or date range]. Our agreement or service-level terms, section [number], provide for [credit or other remedy] when availability falls below [contract threshold].

The service was unavailable or materially impaired from [start time] to [end time]. The related invoice is [invoice number], and the affected subscription is [plan name].

Please calculate the credit under the agreement and apply it to invoice [number] or refund it if the terms provide for a refund. I have attached the outage records, support ticket, and relevant contract section.

Please respond by [date].

Sincerely,

[Full name]
[Account ID]
[Company, if applicable]
[Contact information]

Ask for the remedy promised in the agreement. A service failure does not automatically create a cash-refund right if the contract instead provides for a future account credit.

8. Excessive or unexplained maintenance fee

Use this when an invoice includes a maintenance, administration, support, or similar fee that is unclear or appears inconsistent with the agreement.

Subject: Request for Itemization of Maintenance Fee - Invoice [number]

Dear [Billing Team],

Please place the disputed line under review and confirm the correction or explanation by [date]. I have attached the invoice and the relevant pricing or contract documents.

Use this when you want to end the service and prevent additional billing while resolving a current fee.

Subject: Cancellation Request and Final Account Review - Account [ID]

Hello [Customer Support Team],

Please cancel [service or subscription] effective [date] using the cancellation method permitted under my agreement. I am also disputing the [amount] [fee or charge] shown on invoice [number] because [brief factual reason].

Please confirm:

1. The effective cancellation date
2. Whether any additional recurring charges will be made
3. The final amount owed, if any
4. Any refund for unused prepaid service that is available under the agreement
5. The date and method of any refund or credit

Please send written confirmation by [date]. Until this is resolved, please direct billing questions to [email address].

Sincerely,

[Full name]
[Account ID]
[Contact information]

If the provider requires cancellation through an account portal, phone line, or separate form, use that method as well as sending this written record.

10. Follow-up after the provider does not respond

Use this after your first complaint has gone unanswered or the response did not resolve the billing issue.

Subject: Second Request: Unresolved Service Fee Complaint - Case [number]

Dear [Billing Team or Escalations Team],

I first reported the following issue on [date]: [one-sentence description of the disputed fee]. My account is [account ID], invoice [number], and case number [case number].

The issue remains unresolved. I am requesting [specific remedy: refund, credit, corrected invoice, cancellation, or written explanation] for [amount].

Please provide a substantive response by [date]. If you do not resolve the matter, I will review the dispute process available through my payment provider, if applicable, and consider the appropriate consumer-protection or regulatory complaint route.

I have attached my original complaint, your response if any, the invoice, and supporting records.

Regards,

[Full name]
[Account ID]
[Contact information]

Keep the escalation factual. A clear record is more useful than a threat to cite laws that may not apply.

How to write and send the complaint

1. Check the bill and the agreement

Compare the disputed line with:

Write down the amount you expected, the amount charged, and the difference. A simple calculation makes an overcharge easier to review.

2. Use a precise subject line

Good subject lines include the requested action and a reference number:

Avoid subject lines such as Urgent or Terrible service that don't help the billing team identify the issue.

3. State facts before conclusions

Say, "The invoice lists $79, but the signed order confirmation lists $49," rather than "You are stealing from me." Don't claim that a fee violates a law unless you've verified that the law applies to your payment method, service, and location.

4. Ask for one clear result

A provider is more likely to act when the requested remedy is unmistakable. Ask for a refund, account credit, corrected invoice, itemized explanation, or cancellation. If you're willing to accept either a refund or credit, say so.

5. Attach useful evidence

Attach copies rather than originals:

Name files clearly, such as Invoice-4821.pdf and Cancellation-confirmation.png.

Redact full card numbers, passwords, security codes, and unrelated personal information before attaching files.

6. Set a requested reply date

A date such as "Please reply by [date]" gives the provider a clear target. It is a requested response date, not a universal U.S. legal deadline. A binding deadline, if one applies, may come from the contract, an industry rule, or applicable law. Credit card billing-error deadlines are a separate issue described below.

7. Keep a record

Save the sent email, attachments, automated acknowledgment, case number, and every reply. If you speak by phone, send a follow-up email:

Thank you for speaking with me on [date]. My understanding is that you will [action] by [date].

That message creates a written record of the call without relying on memory.

Credit card billing disputes are a separate step

A complaint to the service provider and a billing dispute with a credit card issuer serve different purposes.

For an eligible credit-card billing error, the FTC's credit card dispute guidance says to write to the issuer so the notice reaches it within 60 days after the first bill with the error was sent to you. Keep a copy of the notice and proof of delivery.

The FTC also says that, unless the problem has already been resolved, the issuer must acknowledge the complaint in writing within 30 days and resolve the dispute within 90 days. These timeframes apply to the issuer's billing-error process. They don't require the service provider to refund you within 60 days.

Use the billing-dispute address and submission instructions shown on your statement or provided by the issuer. Don't assume that emailing the merchant, calling the number on the back of the card, or opening an ordinary customer-service ticket preserves the formal written-dispute deadline.

Include:

Not every disagreement with a service provider qualifies as a statutory credit-card billing error. If the issue is a contract dispute, service-quality complaint, or fee charged by a party other than the card issuer, ask the issuer which dispute process applies.

If you paid with a debit card, ACH, prepaid card, payment app, or another method, the credit-card process above may not apply. Contact the relevant bank or payment service promptly and ask which dispute procedure and deadline govern that transaction.

Subscription and recurring-fee issues

Before sending a complaint, check whether the subscription was canceled, paused, or merely removed from an app or device. Look for:

The FTC advises consumers to understand when and how much they'll be charged and how to cancel. If a company charges you without your consent and won't refund the money, the FTC says to dispute the charge with your credit or debit card company right away.

That guidance doesn't mean every post-cancellation or renewal charge is automatically refundable. The result can depend on the cancellation record, subscription terms, payment method, and whether the charge was authorized.

Common mistakes to avoid

What to do if the complaint is ignored

Follow this order:

  1. Send one concise follow-up referencing the original email and case number.
  2. Ask for a billing supervisor or escalation team.
  3. If you paid by credit card, submit the issuer's formal billing-error notice before the applicable deadline.
  4. If the provider is regulated, identify the agency that oversees that type of service.
  5. If the issue involves a financial institution's handling of the dispute, use that institution's formal complaint process and keep the written response.
  6. Consider a state or federal consumer-protection complaint when the facts suggest a broader deceptive or unauthorized billing practice.

A complaint to an agency doesn't replace a provider refund request or a payment-issuer dispute. Keep each process separate and provide the same dates, amounts, and documents.

Frequently asked questions

Does the FTC 60-day rule apply to every service-fee complaint?

No. The 60-day timeframe described by the FTC applies to the written billing-error process for eligible credit-card disputes. It isn't a universal deadline for an invoice, subscription, debit transaction, ACH payment, or ordinary customer-service complaint.

Should I ask for a refund or an account credit?

Ask for the remedy that matches your goal. Request a refund if you no longer want the service or the charge was taken incorrectly. An account credit may be practical if you plan to continue and the provider's terms use credits for service failures.

Can I dispute a fee that was clearly disclosed?

You can ask the provider to review or waive it, but a clearly disclosed and correctly charged fee may be harder to challenge as a billing error. Check the price, renewal notice, and agreement before describing the charge as unauthorized.

Is a provider required to answer within 14 days?

Not necessarily. A 14-day request in your email isn't, by itself, a universal U.S. legal deadline. Check the contract, applicable industry rules, and the law governing the service for any binding response period.

What is the best evidence for a service-fee dispute?

The most useful evidence connects the charge to the promised price or service: the invoice, original order, agreement, cancellation confirmation, renewal notice, payment statement, and support records. Send relevant excerpts rather than a large collection of unrelated files.

Before sending your complaint, write the disputed amount and the amount you believe is correct at the top of the draft, attach the invoice and the strongest supporting records, and set a reminder for any separate payment-issuer deadline.
