I'm having some translation issues with a Russian kid I'm chatting with, was wondering if anyone would like to translate some small things for me?

This Russian kid stole my Minecraft account, and I'm trying to tell him that although he paid $20, he bought it from not a legit site, and that the account was stolen. He keeps insisting he didn't steal it, which he didn't, but I don't know how to tell him in Russian that he got scammed and that Mojang is going to give me my account back and he lost $20.
