Getting kicked for stupid reason

So , this has happened to me a bunch of times and it is really annoying when u try to play on sostronk.

I entered a match which had aldready started and the score like was 6t:4CT . I joined the ct side and played 1 round with talking really less and playing for trades and was normal . At the start of the next round , i told them i wanted to go a and they requested me to leave. I told i will get a 7 - day ban as i left a match a few days ago like this and got a day ban . They replied with " OK , kick kar sala ko" . This is an issue i face in every alternate match and if some1 can assist me in any way , pls do.
