1. You must go to the People's Bank of China and make an order. It is estimated that your credit record will be affected. If there are bad records, ask the Bank of Communications to issue you a certificate proving that your credit card has been misappropriated, and the People's Bank of China will deal with the bad records.
2. Contact the Bank of Communications department that handles fraudulent credit cards to see how to resolve the matter. Let me give you a reference. This person has similar experiences to yours. It will be helpful for you to see her solution process.
3. If the card-issuing bank does not handle the matter well for you, go to the nearby police station to report the case. You should get better results.
