Kicked out of class for no reason

I was playing as fast zombies on the rp server and was banned from fastzombies,toughzombies, and a zombieantion guard even though ive never used that or the toughzombies. I did nothing wrong or against server rules, all i was doing was killing criminals and cops like it says. The reason someone gave for the ban was because "I was being a dick." I see no reason why i was banned from those characters and I would like that lifted.
My steam profile is 29th_ST•Columbia.

If you could provide more information like what admin banned the jobs (And maybe pictures or video) and who was on at the time etc. etc.

So these staff members have the power to do this that have been on recently...
Brother Lemarties
Swixko
Protector:youtube videogames666
Renamon Toast Crunch
and others I may have forgot but I can only remember these four.

That's just it I don't know who banned me. I was playing as the class, I died then all of the sudden I couldn't join those classes again. When I asked why i was banned no admin answered me the reason why I was banned(I asked a few times"Why was I banned from fast zombies" or "When can I use fast zombies again if I can"). I don't remember which people were admins, I think one or two of the admins(guys who were able to fly) had (-Requiem-) in their names. I didn't have an ingame recording system yet(just got one today) and didn't take screenshots as I didn't even notice I had gotten banned from those characters. There might of been a notice but I don't remember seeing one.

Well I seem to be able to play those classes now so if you helped me then thanks.

Sounds like you got demoted
