Trolls, AFKers, and Feeders

Like many others, I am trying as hard as I can to get to Gold V before the season ends on November 11th. However, I have been demoted twice from Silver I back to Silver II for reasons I believe were out of my control. The first time, I had 76 LP in Silver I and I played 2 games in a row where my ADC DCed. The 3rd game, we had a Nasus who tried said he hated us and refused to group, losing us the game. The 4th game I had our mid laner rush mejais and go 2/14 while our jungle went 0/11, and then I got demoted.

After going through the annoying process of grinding back up through my series again, I get to 54 LP in Silver I, only to have an Udyr AFK in jungle for easy first blood, then another game where we had a Tahm piss off the whole team and start intentionally feeding, and then a game where I went 2/3/15 and another where I started at 5/0/0 in the first 10 minutes. Lost both of those because of feeders and people who won't listen or group.

I feel like I play well in ~90% of the games I do, I stick to champions that I consistently play well as, I don't tilt, I encourage my teammates, I ping wisely, I itemize correctly, I buy wards, focus on CS, I push objectives, but I still get demoted so easily after working so hard to make it up the ranks. All it takes is a couple games in a row with trolls, AFKers, or feeders and I'm completely back to where I started. Probability suggests that these problems should happen on the opposing teams as well, but it seems I have bad luck?

What do you guys do when you come across these teammates while trying to climb in solo queue? Does Riot plan on making the climbing faster to account for these kind of people? I imagine if my skill level permits it would eventually average out and I should climb, but I simply do not have time to play 10+ games per day. What do you guys recommend?
