This is why Platinum is elo hell.

Ok, so it all started in champ select when lets just say Summoner 1, claimed to be a blitzcrank god. He fought with lets say Summoner 2 just to get support, then after that no one talked and we got into game. Summoner 1 goes up to the bot tower and dies to tower and gives their caitlin the first blood. From that moment i knew he was trolling, meanwhile mid lane Summoner 2 was complaining the whole time that we lost and how he had to go to bed and we were only 5 minutes into the game, He was also flaming our top lane tryndamere for no reason whatsoever, so i just muted them both. Then later on in the game i unmute the blitzcrank and ask him to buy a sightstone and he said "i can already see you there is no need for a sightstone." as he is still feeding the enemy team, missing hooks, etc... Like honestly what do i do in the situation? I was Zac jungle and i was trying so hard to carry my team, i went full tank, peeled for our vayne, ganked a lot and we still lost. I ended up going 3-0-6 and i still got an A (lol) and i just don't know what to do, these kinds of teammates happen all the time up in plat and i just need to know what to do besides mute them because muting them doesn't stop them from trolling.

TL,DR: I had trolling teammates and i dont know how to carry them, any tips
