You have 24 hours to refund him his money for the account and items lost (if he has any pictures with proof), or you will be banned. I'm sorry, I've been in a similar situation before, but you have to abide by the rules, just like I have to. Maybe you can work something out with him, that's up to you guys. My time frame right now is 24 hours unless another solution is proposed to me. I hope you guys can work something out, or you repay him to keep from being banned.
Let me know,
