Unfair match making?

Well..its rather self explanatory. I have had many unfair things happened to me while playing league. But these things happen to everyone. So I simply moved on and kept hoping for better. However this time, I think this needs to be addressed. This isn't the first time something like that happens to me. And it must be happening to many others as well.

This link is the match history of my second game for my silver promos. The problem is that in this game, I had to fight silvers and bronze players. My opponent was a silver 2 and I won lane vs him. That isn't even my point. Point is, my own team was made of a bronze 5 and 3 unranked players. How is this fair for my silver promos? My play style is nowhere near comparable to them. I have a really hard time understanding how this happened. I don't mind greater q time honestly. Much better than having to get in a game a quickly lose.
