I have never applied for a credit card of China Everbright Bank. Why are there always dunning messages and occasional phone calls?

Well, there are three possibilities. First, the owner of your card has handled it before, but it is overdue. The bank didn't update his mobile phone number. Now that you have used it, the bank will call you. . . Yes, your credit card was stolen without your knowledge. I suggest you make a phone call. 3, it is a pure fraudulent phone call.
