How to Dispute a Charge on Your Card (Step by Step)

Twin Guides · Money · 6 min read

A wrong charge is not the same as fraud, and banks treat them differently — knowing which is which decides whether you win. This guide walks both paths.

First: is it fraud, or a bad charge?

Step 1: Contact the merchant (banks require this)

  1. Email or chat — keep it in writing. “On [date] I was charged $[amount] for [reason it is wrong]. Please refund within 7 days or I will dispute the charge with my bank.”
  2. Give them one chance and a deadline. Screenshot everything.
  3. Many refund immediately at this point — disputes cost them fees, so “I will dispute” is leverage, not rudeness.

Step 2: File the dispute with your bank

  1. Call the number on the back of your card or use the app's “Dispute this transaction” button.
  2. Use the right reason code in plain words: “canceled recurring charge,” “services not provided,” “not as described,” or “duplicate charge.”
  3. Send your evidence: receipts, cancellation screenshots, emails, delivery records. Disputes are won on paper, not passion.

Step 3: Know the timeline

What kills disputes: waiting months, having no documentation, and disputing charges that are actually legitimate (banks call that “friendly fraud” and it can close your account). Only dispute what's genuinely wrong.
