It does not count as repayment.
If you need to repay 100 for the last bill, and you haven't paid back the 100, you have to deposit 100 on your credit card to be considered as repayment, even if you refund 100 this time, it won't count; if for this bill, you bought two pairs of shoes with your credit card , a pair is 100, ***200, and a refund is 100. When the bill comes out, 100 will be repaid, and the refund 100 will not be included in the bill
