I remember reading not long ago in PC Powerplay that a father wasn't happy with Valve because they labelled him a cheater and banned his steam account when he was 100% sure he didn't use any cheats and Valve got it wrong. He got some legal advice and kept pressuring and by memory he got the account back.
Long story short, if you're definitely not in the wrong with the matter as a consumer don't let it slide. I'd be ******* dirty if this happened to me.
