If you believe you've been the victim of fraud, file a dispute with your bank. Disputes, also known as chargebacks, are a feature of the Visa, Mastercard, and American Express card networks that is intended to protect you, the cardholder, from fraudulent activity (for ex., following a theft or card cloning). The dispute process can also be used to reverse authorized card payments made in justified cases of breaches of consumer rights.
When you file a dispute, your bank passes all relevant details to Stripe, and we use this data in our ongoing effort to combat fraud. Read more about disputing a purchase made through Stripe.
