A chargeback is a dispute against a particular transaction raised by the cardholder (end-user) and reported to their card-issuing bank. A chargeback is a provision by banks and card networks such as Visa & MasterCard to protect buyers from unauthorized or fraudulent payments. Once the cardholder files a complaint, the bank reports the same to Razorpay and initiates an investigative procedure. Razorpay has a clear and simple process to resolve disputes/chargebacks.
