1. Where did the call come from? Just because the other party says CCB, it must be CCB. Now there are criminals pretending to be banks and defrauding you of your money.
2. To ensure that your information has not been used fraudulently to apply for a credit card, you can check whether there is a CCB credit card under your name. You can go directly to a CCB branch to check, or you can call the CCB credit card customer service hotline to check and enter your identity. After entering your credit card number, the phone voice will prompt you whether you have a CCB credit card.
3. It is also possible that the bank made a wrong phone call. For example, the phone number of a certain cardholder who owes money was left wrong, and the bank did not know about it, causing a misunderstanding between the two of you.
