If the credit card refund transaction date of China Merchants Bank is after the billing date, it cannot offset the billed amount 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.
