In this case, you should pay attention to whether you have met a liar. Did you get the phone recording?
A summons is a notice that the court requires the parties to appear in court, and it will not be issued casually. Besides, the court sent someone to the door. Only when there is no one at home will I call to look up the name. It is illegal to pick up the phone and say "you have a subpoena" without asking anything. Even if you have to get a subpoena, I will tell you which court to go to and where. For example, there are two "Intermediate People's Courts" in Shanghai, one in Changning Road and the other in Zhabei District. Just saying "the Intermediate People's Court informed you" exposed the flaw of the liar.
The swindler asked you to press 1 or 2 to ask questions, and he must tell you how much your bank card was overdrawn and was sued by the bank. You said it was impossible, so he asked for your bank account number and password and asked him to check it for you. If you really give him your account number and password, he will succeed!
So don't believe this subpoena when you haven't done anything illegal!
