I have a return from overseas UnionPay. On the day of swiping the card, I found that the amount was wrong. The merchant immediately refunded the money and credited it in 2 days. The refund of overseas UnionPay should be faster than that of international organizations.

If it is an international organization, the business will operate in time, which is estimated to take at least 2-3 working days. Moreover, some merchants may not operate the refund immediately, and this time will be longer. As long as the merchant does quit, it is estimated that it will be received within 3 working days.
