Credit card withdrawal was unsuccessful. After receiving the message of successful withdrawal, I called customer service half an hour later and said that there was no withdrawal record. Is it normal?

If you had a receipt for withdrawing money from the ATM at that time, you should mark * on the column of withdrawing money and reversing, indicating that you have withdrawn money. If you mark * on the column of reversing, it means that the system will automatically reverse the money and the money has returned to your card.

If you don't receive the money back, it's because the ATM of the general bank doesn't have a short message platform, so even if your money has been automatically reversed by the ATM, you can't receive the short message.

If you are really worried, you can call the customer service hotline and ask them to fax your credit card. If there is no such withdrawal transaction, then the account is right.
