You ask him to give you the money back and if not you can still go to court.

Another question would be why are you publishing such senseless questions ?

"How long should somebody date before getting married?"
"Sister, Does your mom know that you get angry at your boyfriend for giving you only one round?"

You won't earn rewards this easily. This platform is created that you can ask and get serious answers. But serious answers are not possible anymore if the question is just pointless.
