Today, someone said he was from the post office, called and said I had a credit card, and asked me if I had a credit card with an overdraft of more than 16 thousand.
This is obviously a liar. Give the other person your ID number. You are drunk, too. You can call the customer service phone of the postal service. "You handled a credit card in the unknown. Even if you overdraw and don't repay, it's not your problem. It's the bank. In order to identify a fake ID card, you are not responsible. You've been cheated.
