I received the information about my repayment, but I have never borrowed money and I don't know this platform. I don't even know the name on the file. What should I do?

To you, this is pure fraud. He lied to you. You don't have to reply. You don't have to worry about it. As long as you are sure you haven't borrowed his loan, don't pay attention to him. There's another way. You can take this information to the police station in your jurisdiction, that is, report it to the police station and tell it to the police station, so that they can handle it and professionals can handle it.
