LF Bronze 3- Silver Solo/Duo ranked

Heyo! I'm currently stuck in ELO hell and I really need some help. I've been getting into real good games till one of my teammates feeds and quits the game or just starts throwing cause there's "no way" we can come back.

My rank is Bronze 3, I main Xayah(M7), Amumu(M7) and Katarina(M7). Feel free to add me!
