Solo Que Ranked

Now I understand that get good is the normal response for climbing, but why am I getting the team mates that need to play things like quinn top vs teemo, zed top vs malphite, tryn top vs nasus and all they do is feed the lane than leave the lane to feed other lanes, how do I attempt to counter that damage that my team mate has done? If i were to dodge every time that i got comps like that I would NEVER play games. I have lost the last 4 ranked games in a row to comps like this, riot please help me to understand why this is something that can effect my elo? (demoted from a climb I made the other day). Now these games have caused me to become quite toxic and now I am trying to teach myself to not talk in games anymore because I am getting the feeling that riot is pairing me with these scrubs as punishment for being toxic.... Thoughts, ideas, tips? (plz no get good)
