Afks

I got to silver 1 this season playing well. But recently it doesnt matter how well i do because most games I have either a troll afk or someone toxic who causes someone to want to troll or afk. I just dont know what to do when someone chooses to intentionally feed. Its impossible to win those games. I just want to know what I can do to climb if I have someone like that every 2/3 games. I know they have a better chance of getting one of those people but it rarley happens that way. Someone help me.
