What should I do if the message of CCB is deleted?

CCB will invite quality customers to adjust the permanent quota from time to time. I have received this message before. Just reply according to the content of the message (I forgot the specific content of the message, just enter the last four digits of the card number, and no other information is required). If your message is deleted, you can call the customer service hotline, and the customer service will help you check and handle it.
