Take the credit card of China Merchants Bank as an example. If the date of refund transaction is later than the billing date, it can not offset the amount payable in the current period, but it can offset the new consumption that has not been billed. Because the refund from the merchant and your personal deposit belong to two different types. It takes a long time for general merchants to refund money. Usually, the money will be returned to the credit card after you make the bill, and the transaction or refund after your bill is actually included in your next bill. Therefore, the refund of the merchant does not actually play a role in repaying your current bill, but it can offset the consumption after your current bill.
After the cardholder pays off the payable amount, the balance in the account is the overpaid amount. When there is overpayment in your credit card account (overpayment of funds or refund after offsetting consumption), the overpayment will be used to deduct your future credit card amount. If you need to get back the overpaid money, you can get it back for free through the Pocket Life Channel.
