Credit card consumption enjoys interest-free period, no handling fee, full repayment within the specified time, and no interest.

Your situation is that you used a credit card to spend money and then returned it, asking for a refund, right? However, it takes some time for the refund to arrive, so your credit card is currently in a state of consumption.

Then what you have to do is to pay back all the money after sunrise (or before the bill is issued) and before the due repayment date, otherwise the accountant will charge interest.

After the payment is returned to the card, it is not recommended that you take it out, because the credit card also charges a handling fee. You can buy things by swiping your card. When there is overflow deposit in the credit card, swiping the card is to give priority to the use of this part of the funds, so that you can spend your deposit without wasting any handling fees.

If you don't understand, please ask. If you are satisfied, please adopt it.
