The way to cancel credit card payment is to ask the merchant to cancel the transaction, so the money previously brushed will be returned to the cardholder's credit card. When the cardholder needs to cancel the order after using the credit card, he can contact the merchant to cancel the transaction and refund the money. It takes 3 to 5 working days for a general merchant to receive a refund.
If you want to cancel your credit card after payment, you should contact the merchant as soon as possible, otherwise you can cancel it only after the transaction is completed and only before the transaction is completed.
