Well, then pass him this message please:

Winning or losing! I believe that you missed the main point. It's all about playing honest and having fun the rest is just minor thing.

And BTW, I didn't cause you on cheating otherwise I would have reported your case to game support which I didn't.
It was unusual case for me so I inquired about it here. In my opinion what you did was worst than cheating.

Good luck!
