Well your KD actually says that you are better than the people you are playing against, how many hours in csgo do you have?
It is pretty easy to go up in rank if you just dont make your teammates tilt and have that type of KD. It clearly seems like your problem is the attitude and maybe you contribute with a bit more negativity than the others do. Instead try to make them hyped so you are trying to win together, if they make misstakes just think in your head that it doesnt matter how bad they are since you can not change everyones playstyle midgame. Just tell them something to try harder next time.
If you really want to go up in level you should work on your attitude in the game.
Thats probably gonna be the best tip for a player like you. Who is not falling behind with the kills. But gets banned multiple times for verbal abuse.
