there is an error in the account information provided by the customer when operating the query. A credit card is a credit certificate issued by a commercial bank or a credit card company to a consumer with qualified credit. Because the account information provided by the customer during the operation inquiry is wrong, there will be a savings card account at the same time, and the account number cannot be found. The customer can check the information and provide the correct information again for inquiry. Consumers with credit cards can go to special commercial service departments for shopping or spending, and then the bank will settle accounts with merchants and cardholders, and cardholders can overdraw within the prescribed limit.
