Pos machine is a successful transaction based on printing receipts. If no customer signs the receipt, the cardholder can refuse to pay. If this happens again next time, continue to swipe your card until the receipt is printed, so you can cancel the previous transaction!
In this case, you can call UnionPay's 24-hour service hotline 955 16, choose manual service, and report the merchant name, merchant number, terminal number and customer card number on the previous purchase order to UnionPay staff, so that UnionPay staff can check whether the transaction is successful.
