You didn't exactly do anything spectacular in any of those games. In fact, one of the games you are the 1/7 score. I am all for liking a champion, but when you lose 9 games in a row all on the same champion in the same position perhaps you should try a different strategy. I looked at all of the people's match histories who you are complaining about and most of their histories look better than yours. For example, 2 games ago, your riven went 4/13/15. The game before that one, the same person went 8/0/9 on Viktor.
Even if it is your teammates' fault that you are losing all of your games recently, which I highly doubt, it isn't like Riot is omniscient and knows that they will do poorly that specific game so they get placed with you.
If your mentality is that it is always your teammates' faults then do you get carried in every game you win? Is Riot setting you up for a streak by stacking the teams when you win 8 games in a row? The teams you get are entirely by chance. It is up to you to make the most of what you are given and try to accommodate each person's style or give them helpful pointers instead of flaming them making them play worse which I am betting is the case by your attitude in this post. No one wants to help a rager win their games. I'm more than happy to lose a game just to see some people on my team lose.
