AFK in ranked issue especially in bronze and silver

So i am in bronze 3 at the moment and one issue i have encountered while trying to reach higher ranks is the consistent amount of trolls and afk players through my games at one point i hit bronze 2 and had a whole day to play, i played 12 games and 6 of them had players who fed a lane about 4 kills then dc and the other 2 had people inting and going 0/20 so i ended up back at bronze 4 this revolving issue has made me, as a consistent player feel the need to become very toxic something i generally try to stray from and not be able to get into higher ranks where i can enjoy the game more because my skill level at this point is way higher than a average bronze player.
