Kicked from Sov-corp with no warning/reason.

So Ive been running with a small mining corp for a little over two months now and I am relatively new to the game (Started playing in March 2017). I met some great people who showed me the ropes and taught me how to survive out in null and made some great friends. All that changed this week when a CTA was issued by the Alliance and I responded and got on comms for the first time however i did not have a mic and could not verbally respond. That was fine. The problem came a hour or so before form up when the pvp director called me out on TS for having my microphone muted. I replied and said I could not change the setting that that displayed as microphone with an X beside it. I guess since TS did not detect a mic on my comp? Fine. I was told to get a mic asap. However the very next day another CTA went out and i was called out yet again and was told that me not having a mic was just an "excuse" as nearly everyone in this day and age should have one. Choking on anger I bite my tongue and apologized and once again reiterated I would get one asap however not a couple hours later I was kicked from the corp and now I have a couple billion isk worth of assets stranded in null. Ive sent a mail to my Ex-Ceo and the PVP director of the Alliance about why I was booted and have not received a response. At this point I don't want to be reinstated after the way this whole ordeal was handled and the only thing I want is to get at least some of my assets out and fire sale the rest to recoup my losses. Was I a victim of paranoia or was it because they are a bunch of elitist pricks. Any thoughts??
