Do you have several credit cards in a bank? Then you must repay these credit cards separately, instead of returning a total amount to one credit card. There should be a clear notice on the bill, which is the repayment amount of each card. So when you go to the outlet to repay, you must hand in the card numbers of several credit cards and explain them clearly. In the case of multiple credit cards, it is more convenient to go through the agreed repayment procedures in advance, and there is no need to worry about repayment.
