Unfair Matchmaking

I have been getting unfair teams lately and it has been getting out of hand. I usually go against players way above my elo. I an silver and have been going against golds and sometimes plats. It recently got way out of hand and i thought it was very unfair. I had 2 silvers(including me) and 3 unranks on my team and the enemy team had 1 challenger, 1 gold, 1 platnium, and 2 silvers. This match making is very unfair and I hope you can do something about it.
