Seeing a charge you don't recognize, or one that's wrong, can make your stomach drop. The good news is that card issuers handle these calls constantly, and the process is fairly structured. Your job is to give clear facts; their job is to open an investigation.

There are two common situations. The first is a charge you don't recognize at all, which may be fraud. The second is a charge you recognize but that is wrong: you were billed twice, charged the wrong amount, charged after cancelling, or never received what you paid for. The script below covers both, and the rep will usually ask which applies.

In many cases, it helps to contact the merchant first for a billing error with a business you know. Your card issuer may ask whether you have. If you haven't, the issuer may still help, especially with suspected fraud, but having tried the merchant strengthens your case.

What to have ready before you call

  • Your card and the account holder's details
  • The date, amount, and merchant name exactly as shown on your statement
  • What you expected to be charged, if anything
  • Any receipts, cancellation confirmations, or emails with the merchant
  • Notes on any contact you've already had with the merchant, including dates

The script, step by step

Your opening line

Hi, my name is [your name]. I'm calling about a charge on my card ending in [last 4 digits] that I'd like to dispute.

  1. Identify the charge

    The charge is from [merchant name] on [date] for [amount].

    Read it exactly as it appears on your statement.

  2. Explain in one sentence

    [I don't recognize this charge / I was charged twice / I cancelled on (date) and was still charged / I never received the item].

    One clear sentence. Details come when they ask.

  3. Share what you've tried

    I contacted the merchant on [date] and [what happened].

    If you haven't contacted them, say so honestly. The rep will advise.

  4. Ask about next steps

    What happens next, and is there anything you need from me?

    Banks often send a form or ask for documents. Ask how and by when.

  5. Ask about the card

    If this might be fraud: should this card be cancelled and replaced?

    For unrecognized charges, protecting the account matters as much as the refund.

  6. Get a reference

    Could I get a case or reference number, and the expected timeline?

    Write it down along with the date and rep's name.

If they push back: calm answers

These are things the other person might say. Read them now so nothing catches you off guard. You can rehearse them in practice mode.

Have you contacted the merchant?
Yes, on [date] I [called/emailed] and [result]. / Not yet, I'm not familiar with this merchant at all.

Honest either way. For a known merchant, they may ask you to try them first.

Is it possible someone in your household made this charge?
I've checked with [household members], and no one recognizes it.

It's a routine question. Answer it directly.

We'll need you to submit documentation.
Sure. Where do I send it, and what's the deadline?

Get the method and the deadline so nothing expires.

This looks like a valid charge from a merchant you've used before.
I understand. The issue is [specific problem: double charge / charged after cancellation]. I have [confirmation number / email] that shows this.

Point to the specific error and your evidence.

The charge is still pending.
Okay. Should I wait for it to post before disputing, and if so, how long?

Some issuers can't dispute pending transactions. Ask when to call back.

If you get voicemail

Hi, this is [your name]. I'm calling about a charge I'd like to dispute on my card ending in [last 4 digits]. Please call me back at [your phone number]. Thank you.

Say your number slowly, and repeat it at the end. More in our voicemail guide.

After the call

  • Write down the case number, date, and timeline in one place.
  • Submit any requested documents promptly and keep copies.
  • Watch your account for a temporary credit and for any letters or messages from the issuer.
  • If you received a replacement card, update any legitimate automatic payments.

Log names, times, and reference numbers as you go with the free Call Notepad and hold timer.

Frequently asked questions

Should I call the merchant or my bank first?

For a billing error with a business you know, contacting the merchant first is often faster. For a charge you don't recognize at all, contact your card issuer promptly.

Is there a deadline to dispute a charge?

Issuers and card networks have time limits, and they vary. Call as soon as you notice a problem and ask the rep what deadline applies to your situation.

Will disputing a charge hurt my credit?

Asking your issuer to investigate a charge is a routine account service. If you have questions about your specific situation, ask the rep directly.

What's the difference between a dispute and fraud claim?

A dispute usually involves a merchant you dealt with where something went wrong. A fraud claim involves charges you never authorized. The rep will route your call based on which applies.
