At present, banks handle refunds in different ways, and ICBC gives priority to deducting the corresponding consumption. According to the regulations of China Everbright Bank, if the cardholder generates new consumption after the bill date, it will be offset by the balance in the card first. China Merchants Bank shall keep accounts first, and after the new bill is cleared, it will be offset by the previous refund on the repayment date.
In short, although it is returned money, it is handled differently according to the regulations of different banks.
