Placement Matches are Rigged

Tried to get Bronze on my smurf. Went 4-6 (Left the last match and got LeaverBuster). Got placed Silver 3. SILVER 3!!! I get carried even when I try my hardest to feed. Riot fix this please for the players that want Bronze. My team holding me back from lower ELO.

EDIT: This is a serious post. I actually wanted Bronze :c
