Credit cards generally don't deduct money for no reason. After all, it's all from the bank. If the customer's credit card is deducted by the issuing bank, and the customer does not know the cost, he can call the customer service staff of the issuing bank. It is possible to deduct the annual fee, and customers should pay attention to repayment on time afterwards.

If it's not an annual fee, let's see if it's deducted after some business. Or did the credit card fail to pay off the bill on time after the cash withdrawal, resulting in interest, and the bank automatically deducted money from the card because the credit card signed an automatic debit agreement.

The customer had better check whether the card has been stolen by others. If there is a credit card risk, you must quickly lock the account, contact the bank for handling, and check the recent transaction details to see which merchant swiped the card. And if the bank only deducts money repeatedly or wrongly, the bank will return the wrong money after the customer reflects the problem.
