Trolls everywhere

I am only a silver player but I was silver 2 on my way to silver 1 earlier today. Now I am silver 4 after 12 straight losses. I mean what is with the matchmaking system??? If someone feeds you should delete way more LP from them and get them into bronze or iron, i's ridiculous. The amount of trolls I encountered during this was unbelievable. Maybe it's because it was New Years day but I never experienced so many inters and bad poor sport people ever in league. I mean I had actual inters like 4 of them...not just someone that sucked but someone that was inting. I had a tahm kench that would spit you at the enemy when you were low health to get you killed and then laugh in game after you died. I had a Bard support that took smite and last hit all my jungle creatures while I was soloing them for farm to steal them from me. Riot you have to do something about this or the only game mode left to play is a 5 man flex. Alas I don't have enough people online to play 5 mans all the time. It has really turned me off to the game. This is the worst I have ever experienced and it's getting worse, I have been playing since season 2.
