Is Riot out to get me?

So I have failed the past 7 series to be promoted into Silver II, in my 2 most recent series I have had 4 disconnects in 4 games. All 4 leavers rage quit due to negative comments from my teammates, I try and mediate the situation by advising to mute each other and just keep playing, but to no affect.

I win most of my other games, and I have a decent KDA so I'm not completely carried through the ladder, but after 2000+ ranked games I nearly always lose in my series due to feeders or leavers... and they ONLY show up in my games during a series, they are absent in regular matches.

One time during my first match in a series I had 2 trolls, I reported them after then even blocked their summoner names, and the next match in that series BOTH of them showed up in my game and caused a second loss and ultimately cost me my series.
