after the bank of communications credit card is blocked, the cardholder should first find out the reason for blocking the card. If the card is blocked due to overdue repayment, the cardholder should immediately pay off the arrears in full, and then call the customer service phone number of Bank of Communications at 4-8-9888 to apply for unblocking.

if the cardholder is blocked because he is suspected of cashing out, he should immediately stop the suspected illegal use of the credit card, such as frequent large-amount purchases and large-amount withdrawals. Cardholders can submit invoices and other materials to the bank to prove that they have not cashed out and apply for unblocking their credit cards.
