Agreeing with Tony, here. He didn't have to send the games back and there's probably nothing you could have done about it.
Not sure honestly. We aren't talking here about $12 in cheap jewelery but a tidy sum of cash. Probably would have to talk to a lawyer realistically and since it crossed state lines it'd be a felony if there was any wrong doing on his part.
I fix things. You name it, I'll work on it. Want something modded? Recapped?
