First of all, I suggest you call the customer service to inquire about the situation, try to cooperate with the customer service, don't worry, communicate with the customer service patiently, and try to confirm whether there is a card in your name from them. It's best to let him confirm through his ID card to prevent the phenomenon of duplicate names. In fact, there are several possibilities for this situation: 1, and the whole overdraft letter is forged by a fraud gang, which means that you don't have this situation. I lost my ID card, and someone used it to get a credit card, which may have been borrowed by my company or relatives and friends. So I suggest you contact customer service and ask if 1 has a card. If you have a card, try to ask the customer service to tell you when you got it (it can help you remember the situation at that time, such as where you were, what company you worked for, and make sure you have done it). 3) If all the above situations exist, but you didn't handle them yourself, I suggest you call the police and cooperate with the police, and ask the Bank of China if there is any way to cooperate with the routine investigation. And cooperate with the Bank of China to assist the police in the investigation.
