When the cardholder finds that the credit card is lost, if he wants to apply for freezing the credit card, he needs to call the customer service immediately to the issuing bank, and then explain the current situation of his credit card, so that the customer service staff can help freeze the credit card as soon as possible and avoid any economic losses. It should be noted that some banks' credit cards are frozen for a short time, only until the next day 15:30.
