Blizzard being Blizzard

Hey all, account has been suspended for unfair play. I am fairly certain this is some kind of boosting issue as I've been playing with a friend who is brand new and placed around low masters which is where my tank rank is. We won games but my tank rank is genuinely masters so I don't really see the issue. Seems someone just got butthurt and spam reported us because he's also been suspended for two weeks. This is the first action taken on my 9 year old account and i can't say I'm very happy about it, anyone has any clues how I could appeal. Do keep in mind majority of this is assumption but battle.net says Im suspended for unfair play and I don't play with team or match chat on which I understand is a common pitfall for players being banned
