1, the number is incorrect: it is possible that the previous owner of the phone number you are using handled some business in the Agricultural Bank of China, such as loans and investments. The bank called this number, not the person who handled the business before, so you are very puzzled! I don't know how long you have used this phone number, so I'm not sure.

2. Credit card: Did you apply for a bank credit card with this number? Is the credit card overdue or unpaid? Another possibility is that if you swipe your credit card, the information may not be leaked.
