they are unreasonable not to give any proof they want to appropriate the money i deposited in the amount i won total 2,200$
There is no accusation against them so far but yours only. Maybe they are really that good and you really have cheated otherwise they won't just do this with just $2,200.
But yep you may try that askgamblers suggested above. That's one way to do it for you to be heard since they already stated it's final. They seem to be confident in their decision and there could be truth to what they are saying. Sorry for your loss.
When it comes to scams, it makes no difference if the capital is large or small; they wipe off everything. Blizz.io is a legit site where gambling odds are activated for the aim of generating profits, but it hasn't happen to me or any one I could think of, and no one has the right to speak or share scam accusation about their site until it is proven guilty, especially when the transactions are suspect. I don't blame the Blizzard staff for deleting the account; after all, it was their breached terms and conditions that caused them to want to discover and remove any problematic accounts. After all, this is not the greatest place to air your grievances; rather, it should be done in the reputation board, where vital information about blizz.io will be disclosed, for better or worse.
