To dispute an overcharge on your bill, send a written notice to your creditor's billing inquiries address within 60 calendar days of when the incorrect charge appears on your statement. Federal law under the Fair Credit Billing Act requires creditors to acknowledge your dispute within 30 days and investigate it within two billing cycles or 90 days, whichever is shorter. Knowing the exact steps and deadlines matters because telephone calls or emails do not trigger these legal protections—written notice is the only form that counts. Missing the 60-day window or sending your dispute to the wrong address (such as the payments address instead of the billing inquiries address) can cost you the creditor's obligation to respond and investigate.

The 60-Day Window and Correct Address
Timing is everything. you have 60 calendar days from the date the overcharge appears on your statement to send written notice of the billing error. This deadline is firm: disputes sent after 60 days lose the federal protections that force a creditor to investigate.
Your written dispute must go to the billing inquiries address listed on your statement, not the payment address. Sending it to the payments location allows creditors to claim they never received proper notice, leaving you without legal recourse even if your dispute was correct.
Check your statement for the separate billing inquiries or customer service address. Include in your written notice the amount of the disputed charge, the date it appeared, a description of the error, and your account number. Keep a copy of everything you send.
The Investigation Timeline and Your Credit Protection
Once your creditor receives your written dispute, it must send you a written acknowledgment within 30 calendar days. This acknowledgment tells you the creditor received your complaint and will investigate. The actual investigation must be completed within two billing cycles or 90 days, whichever is shorter. During the investigation, the disputed amount cannot be reported to credit bureaus as late, delinquent, or unpaid.
The creditor also cannot attempt to collect the disputed amount, charge interest on it, or restrict your account—though they can report that you dispute the charge. This protection matters: an incorrect negative mark during a dispute can damage your credit score for months. The creditor must send you a written explanation of its findings when the investigation closes, stating whether it upheld your dispute or found the charge correct.
Evidence That Strengthens Your Dispute
Successful disputes rest on documentation. Gather receipts, invoices, canceled checks, transaction IDs, and email confirmations showing the correct amount you were supposed to pay or proof that the service was not rendered. If the merchant failed to deliver, screenshots of the cancellation request or customer service emails help prove your claim.
For overages on existing services, include your usage history if available. For duplicate charges, show when you were billed and proof that you paid already. For charges after you canceled a service, include the cancellation confirmation. The more specific your evidence, the harder it is for the creditor to dismiss your dispute. Keep all communications with both the merchant and the creditor. If the merchant refunded you but the charge still appears on your card statement, save that refund receipt—it proves the dispute's merit.
Subscriptions, Utilities, and Special Billing Rules
Unauthorized subscription renewals are disputes you can file immediately under the FTC's Negative Option Rule. If a subscription continued charging after you canceled, the charge is unauthorized and subject to immediate refund through your card issuer. Federal law requires merchants to send clear advance notice before charging and to make cancellation easy.
Utility and telecommunications bills have their own rules. Many states guarantee one free meter accuracy test annually and require resolution within 30–60 days. File a complaint with your state Public Utility Commission if your dispute with the utility remains unresolved. Telecommunications carriers must display a toll-free dispute number on your bill and cannot charge for unauthorized services.
What Happens If Your Creditor Breaks the Rules
If a creditor violates the Fair Credit Billing Act's procedures—such as failing to investigate, missing deadlines, or not sending a written explanation—the creditor loses the right to collect the disputed amount and related finance charges, regardless of whether the charge was actually correct. This is a powerful enforcement tool: a creditor's failure to follow the process bars collection entirely.
Beyond losing the disputed charge, you can sue the creditor. Statutory damages range from $100 to $1,000 (or twice the finance charge owed, whichever is greater), plus actual damages, court costs, and attorney fees. These fees mean you can afford a lawyer without paying out of pocket—the creditor pays if you win.
Frequently Asked Questions
Can I dispute a charge by phone or email?
No. Only written notice (by mail or documented letter) triggers Fair Credit Billing Act protections. Telephone and email disputes have no legal standing and creditors are not required to investigate them.
What if the creditor says it investigated and found the charge correct?
If you disagree with the creditor's finding, you have the right to dispute that response in writing and can add a statement to your credit file. You can also file a complaint with the Consumer Financial Protection Bureau or pursue a lawsuit if the creditor violated investigation procedures.
How long can the creditor hold the disputed amount?
The creditor cannot collect or charge interest on the disputed amount during the investigation (up to 90 days). After the investigation closes and the creditor reports its findings, you owe the amount only if the creditor found the charge correct.
