There is an important difference between cancelling a subscription and disputing a charge, and using the wrong approach can cause problems.
Cancel first, then dispute if needed. Always try to cancel directly with the company before filing a dispute with your card issuer. If you dispute a charge without cancelling the subscription first, the company may send your account to collections or continue to bill you.
Dispute when the company will not stop charging you. If you have cancelled and the company continues to charge your card, that is the right time to file a dispute. Attach your cancellation confirmation as evidence.
Dispute unauthorized charges immediately. If you see a charge from a company you never authorized, file a dispute right away. You generally have 60 days from the statement date to dispute charges under the Fair Credit Billing Act.
Your credit card issuer's dispute process is typically available through their app, website, or by phone. Most disputes are resolved within 30 to 90 days.
