What can be put on file is fraud, but there may be a limit on the amount of money to put on file, depending on the situation.

Actually, thinking about it is not a good thing. Suffering is a blessing. He cheated you with a mobile phone, but what he lost was his conscience and the complaints in your heart. He's not worth it. You just lost a mobile phone, but it made you see that a person will cheat you more if he keeps pretending. Good people lose the most, but they always get some. Evil people will try their best to get the most things, but in the end they don't belong to themselves.
