Tired of losing because of trolling team mates

It's so annoying, I try my best and by the time I'm ready to carry our inhib is down and the team has a negative (and I mean NEGATIVE) KDA, just look at my previous Ranked flexes on nasus, I just can't deal with this, it feels so unfair to not be rewarded for trying and to be stuck with disrespectful players who do nothing but /all chat all game and proceed to lose all lanes single handedly.
