Trolls and Bad Players

So I finally fixed my internet issue for a week straight and the first game I get into I see a 1/13 Jax against a rumble. A "support" Thresh not landing a single hook and flashing on 1v3's. I see a Kayle that said that he only ganks the winning lanes. And a good Anivia then me as ADC. What the fuck is that? Why did I have to deal with that dynamic team? They're were all trolls but Anivia. Jax is broken atm and he goes 1/13? That has to be intentional. It was only to Ashe too. All his deaths were ashe's kills. Yet they report me for saying something about them trolling me. Reports won't do anything either. I have proof of Thresh saying i'm trolling a bit. I have proof of him boosting aswell. I know one of his friend on his list and he sent me pictures of that same Thresh asking to get boosted and videos. I just want to know, why me? Out of all the league players, I have to deal with this shit.
