What to Say When Disputing a Charge

Last updated: July 31, 2026

Call the number on the back of your card and give three facts: the date, the amount, and the merchant name exactly as it appears on your statement. Then say what you want: "I did not make this purchase. I'd like to open a dispute and have a provisional credit issued while it's investigated." Do it within 60 days of your statement date. Scripts for unauthorized charges, double charges, and charges after cancellation are below.

Why this call feels hard

Calling to dispute a charge feels confrontational. You're essentially saying "this is wrong" to a person on the phone, and there's a nagging fear that you'll be accused of lying or that they'll refuse to help. Maybe you're second-guessing whether the charge is actually an error. According to a 2023 Consumer Financial Protection Bureau report, credit card billing disputes rose 50% between 2019 and 2023, so you're far from alone. Banks and credit card companies handle these calls every day — they have entire departments for it. You have legal protections. This is a routine process, not a courtroom.

Before you call

Script: Unauthorized charge

You say

"Hi, I'd like to dispute an unauthorized charge on my account. On [date], there's a charge of [amount] from [merchant name]. I did not make this purchase and I don't recognize this transaction. I'd like to open a dispute and have a provisional credit issued while it's investigated."

The rep will ask you to verify your identity and may ask whether your card was lost or stolen. If it wasn't, they may issue a new card number as a precaution. Ask how long the investigation will take — it's typically 30 to 90 days for credit cards.

Script: Double charge

You say

"Hi, I have a duplicate charge on my account. On [date], I was charged [amount] by [merchant name], but the same charge appears twice. I should only have been billed once. Can you reverse the duplicate?"

Double charges are common and usually easy to resolve. The rep may suggest contacting the merchant first. If the merchant already told you to call your bank, say so: "I've already contacted the merchant and they directed me to my card issuer."

Script: Charge after cancellation

You say

"Hi, I'm being charged by [merchant name] for a service I already canceled. I canceled on [date] and have a confirmation [number/email]. The charge of [amount] posted on [date]. I'd like to dispute this charge."

This is where your cancellation confirmation number matters. If you have it, the dispute is straightforward. If you don't, explain the circumstances — when you called to cancel, who you spoke with, what you were told. The bank will contact the merchant as part of their investigation.

Tips

Common questions

What do you say when disputing a charge on your credit card?

Call the number on the back of your card and say: 'I'd like to dispute a charge on my account. On [date], there was a charge of [amount] from [merchant name] that I did not authorize.' Have your account number and the specific transaction details ready. The bank will open an investigation and typically issue a provisional credit.

How long do I have to dispute a charge?

Under the Fair Credit Billing Act, you have 60 days from the date the statement with the disputed charge was mailed to you. For debit cards, the Electronic Fund Transfer Act gives you 60 days as well, but your liability increases if you wait more than 2 business days to report unauthorized transactions. Call as soon as you notice the charge.

Can I dispute a charge if I already paid it?

Yes, you can still dispute a charge even if you've already paid your credit card bill. The Fair Credit Billing Act protects your right to dispute billing errors regardless of payment status. Contact your card issuer within 60 days of the statement date.
