Recovering account

[xX-RISE-Xx]

So the other day, one of my enemies managed to steal my steam account, and recovering it is impossible because I traded it from a friend.
So now I want to recover his runescape account, move his money to my account, and tell him if he wants it back, he has to give me my steam account back.
So I tried to hijack his email with success, and tried to recover his account for 12 times. They always come back with "details dont match."

So, to take his account, what would be a good way to make the recovery form look reasonable? Like an infallible plan?

@zazack, all I have is the membership payment. No password/acc creation
