What should I do to climb in rankeds?

I'm done with this. Every single time there's a bad team waiting for me(I know, usual blaming and crying, but I'm just looking for advices) it seems like this is all made up to make me lose games, specially when I reach my promos after a cool winstreak with non toxic teammates. I don't know what to do anymore to climb up, everysingle time 2 lane's feed and I lose the game. When it reaches the late game, the team just doesn't do proper decisions and as toxic and bad they are, they separate and part of the team runs away while the other ones are fighting and focusing the wrong people. I don't know what to do anymore to climb up, I stopped talking in order to not receive more punishments for trying to teach people what to do and give them tips, I'm actually playing well but the team never seems to help. I'm silver and I'm wondering what should I do to climb up to gold or above where I actually learn something about the game and improve as a player (I feel I'm not doing it anymore in silver) and don't have bad teams ruining my games? https://imgur.com/a/hMxnyQR -- Two of my scoreboards.
