Account suspended after doing nothing wrong

I have just had notice that my account has been closed in Warcraft Rumble having done nothing wrong whatsoever. I did not abuse the gold bug back in December nor have I engaged in any kind of behaviour against the terms of service.

I was engaged in PvP matches earlier today when I became stuck in a loading loop trying to load into a match (loaded from 50% to 100% then returned to Blizzard Entertainment screen, then repeated this over and over). This was not the first time I’ve been caught by this loading loop bug, so I simply closed the game and went on to do something else.

Now I check my email to find my account permanently closed, having done nothing wrong myself and what I can only think as being the victim of a bug that is representing as more sinister behaviour.

I cannot understand for the life of me, what is going on and why such an action has been taken. I should add, this is also after I’ve made significant investment in the game. Any help would be greatly appreciated.
