can someone at riot fix my mmr

i seem to be getting super low elo players to coincide with me getting gold/plat level enemys. I would like you to raise my mmr so I play with players around my skill level instead of 20 min stomps of my teammates. Much appreciated. As much fun as it is wasting over 20 min afk (they dont surrender even if there is a motha fuckin fire) my last game was 9-3 with me afk for 10+ min due to it being that over. I was leveling up a smurf and had players that were actually new better than these 30's. So why are they matched up with plats/diamonds? ohhh maybe because i sometimes play with my silver friends is why my mmr is so fucked! yo riot fix this shit thanks before i get banned for calling the flaming r%%%%%s flaming r%%%%%s..
