Suspensions gone overboard? who to talk to?

NEVER happened to me before... I've friendly fired accidently a few folks (always apologize!).... and I have even team killed by accident playing arty quite a few times... NEVER a BAN? I don't feel that my play was malicous or in any way offensive, just stuff happens in quick moving battle kind of thing.... but a BAN? btw  9400+ battles, so no noob to all the 'crap' that happens out there...   To whom can I appeal, write to, log my complaint? any direction appreciate, as I've looked all around and can't find any proper contact point for anyone 'in charge' of discipline... Thanks!
