We were in the same game and the same thing happened to me

I joined the server with two other people in it, some others joined after on killhouse, I was using the famas which is known to be a one burst and after I killed someone with it and shot gunned someone else I got banned for cheating? The ban honestly doesn’t make sense since I was missing alot of my shots and was killed 4 times in a row so I couldn’t possibly have been cheating.
