When you receive the activation message, it means that the card has been processed, but the landlord has not received it, but it has not been returned to the bank, so the bank doesn't know that you haven't received it, and you haven't called the bank to tell you, so the bank will send a message to remind you to activate it. Call the customer service hotline of CCB as soon as possible to explain that you haven't received the card for three months, check the address, and then they can reissue it for you. When issuing a card, CCB will send a short message to remind you. The content of the short message includes the card number, the last four digits of the card number, the approximate receiving time and the way to inquire about the mailing situation. Please pay attention.
