I submitted the information. Got a call from the Beijing court. Say you'll sue me if I don't pay? What to do?

You submitted the information and received a phone call from the city court, saying that you would sue if you didn't pay it. Analysis: You must have encountered online fraud. The court is the referee in the middle, not the plaintiff. The plaintiff had no defendant before the prosecution and could not contact the "defendant" in advance. If the plaintiff sues you, you will receive the complaint first, not the phone call from the court.
