Banned for the company

Hello, my cd hash 243078e8741530e37af727de9ab9ca77.
My in game name Yellow_Syndicat.
I was banned about three days ago. I do not understand the reason for the ban.
The player wrote a complaint against me and several other players for stealing assets and team kills, but I've seen no one teamkilling and was in a squad called APC, I didn't insult anyone did not write anything in the chat.
I do not really understand the conflict situation occurred between the players. Almost the entire round I was stranded on an island and fought on points.
is it possible to unban me?

Yes, my nickname where indicated, but what exactly is my fault? maybe the admin who banned me to describe the reason for my ban?

Stealing assets
Duplicate squad
Teamkilling
False reports
Grieifing

but I didn't do anything of the above list.
I read the complaint of the player, watched his videos, there's nothing about me, my nickname is written in the title of the complaint and only.
I was banned without checking the case, the player who wrote the complaint about me - didn't provide any proof about me and you banned me just with his words?
how long am I banned? is it permanent?
