D3 thinks I'm... CHEATING!?!?

I contacted D3 because of persistent "Connection Failed" issues. They responded by saying that my account has been flagged as exploiting Deck Wars.

Seriously, in what way have I cheated? I hate cheaters. Playing the game within the parameters that they set is not cheating. I feel like I've wasted my time and money on this stupid, stupid game. Well, not that much ($5 + $3). Still, this is very disappointing.

UPDATE 2015-08-15 Looks like I'm not the only one experiencing this. Check out this reddit post: https://www.reddit.com/r/CardWars/comments/3h2e0n/any_idea_why_d3_would_flag_my_account/.

I hope D3 gets their heads out of their asses and stops pissing off the players. I know I, for one, will never buy anything from them ever again.
