Afkers in Game

So I'm in my placements on my account, and for the past 3 games, there is an afk or feeders in my game afked after level 4, and I'm fine with the feeders, cus they tried their best and all, but the afkers, I really don't think it is fair that it lowers my matchmaking rating because we lost because of the afk. Is there anything that someone can do?
