League tips DONT HELP

So i tried to not be toxic as much as possible every time i lose a rank i would legit just chill and refresh myself before even taking the time to play a game but LEGIT two days ago i was playing 6 games of rank and i lost all of them i lost 2 of them because i DID bad and did not know the match ups that well but the other two games were just "My teammates" despite me trying to be friendly as possible and actually tell my team "we can still do this just play safe" my team mates refuses to listen and act like they're challenger tier just a few moments ago i HAD a game where my and and Vayne act like they can 1v5 the enemy team despite be pleading them to group and pinging ONCE for assistance. i swear to god i feel like riots is rigging their system and is putting me with these "PLAT" players. Seriously man idk what i did to deserve these type of games unless riot REALLY wants me to be as toxic as hell too then i guess. I'm just done with having these type of team mates that refuses to work together and act like they control the game when in reality it's a TEAM GAME.
