My CITIC credit card sent a text message saying that it was necessary to withdraw cash. Why didn't you respond?

Generally, fixed-line banks will not send messages or call you to raise the amount. Under normal circumstances, they will call the bank's customer service phone to apply for withdrawal. If a bank calls you to send a text message or call you to help you withdraw cash, ask you for the information verification code. It may be fraud, in case the credit card is stolen. It's best to call the customer service phone of the bank to see if you have received the text message!
