Call the credit card customer service of CCB. If the issuing bank needs to provide the receipt of the declaration when handling non-personal transactions, it can ask the customer service for the work number and fax number and fax receipt.

However, if the cardholder's personal reasons lead to information leakage and the card is stolen, the issuing bank may still need the customer to bear it. In addition, there is the risk that the card will be stolen, depending on whether the cardholder chooses to modify the transaction password or directly contact the card issuing bank to change the card.
