Win streak=Losing streak

Legit 3 times in a row that i go on a wining streak and its followed up by a massive losing streak. Climb to gold 3 and lose so many games i'm down to gold 5 0LP. 12 game losing streak matched up with some of the most toxic people who legit give up 10 kills in 10 minutes games are over before they even start i'm getting so pissed off grinding for days just for it to all get messed up by YOUR matchmaking it makes me feel like playing this game is a complete wast of my time.
