If you have filed a complaint using your console that is all you can do.
Just to mention something as you may not be aware but naming and shaming other members in this way is against the forums CoC. No matter what you believe they may/may not have done these forums can not be used to report players.
If you have not done it already be sure to block communications and set this user as an avoided player, the XBLPET will take it from there and take what ever action they deem appropriate..
