This number is the dunning phone number of CCB. Your credit card should be overdue. If you have any questions, you can call this number back. It's not false news. Once I forgot to pay the loan, I also received this short message and dialed this number back. It's really from CCB, don't worry. In other words, you should pay back as soon as possible after receiving this message, otherwise it will affect the use of cards and credit.
