Feeder teammates and toxic attitude(mute button for second one, but what for first one?)

Hello everyone, I have a simple question, why do I have like 1 normal game with normal enemy team and my team and then 5 games in row enemy team such a good and my team ultimate feeders who are also toxic as hell? I mean is there any curse made that u cannot rank up in divisions or what is going on? and why its almost every time hittin' me? I clearly say on start of the game lets be team lets play safe farm and make good decisionmaking, im pining to go back im pinging when my lane is missing, when enemy lane is missing when jungler is missing and im pinging where are they going - which direction, and after all those pings my teammates just don't wanna listen to it they keep pushing and dying, ok i mean that can happen one game, or one time or even two times, but why it happens 5 games in row and 10 times per 1 game? Why I just get so bad teammates who doesn't even trying to win in ranked games, that isn't fair at all! They always have some excuse why they died why they couldn't go back etc and they keep doing the same mistake all over again, im honestly without any point what to do and how to rank up in this game i feel so bad guys, i had surgery so i have much time to play im off from my job like next month and half and i really dont wanna tilt myself in games, i want to have fun, stay calm etc. i can take 2, 3, 4 games with those people but why am I keeping to get matchmaked 5 + games with those kind of people? i have 10 more wins than defeats that means my mmr cannot be in hell... im gold 3 at the moment and I keep getting matchmaked with people silver 3, 4 etc. atleast 2 of them per game and 2 guys higher division 1 or 2 than me. I do everything i roam to help i ping to go back i ping when to go for objective when to go for fight and those are all clear pings im playing this game for 9 seasons, im being diamond season 5 and all after that ended up in platinum.... i got game knowledge and i can be able to carry team with just using smart pings and roaming when its needed to help someone, but people are really not interested into win, they die 3 times in same way and they just decide to int, they decide to chat instead of farming and trying back to the game etc. im helpless, can someone explain me why those people getting in matches with me and why is this happening to me, who and why is preventing me to rank up and enjoy this game? I wouldn't be typing this here. Don't say me stop playing that day... I stopped playing after 3 int games i come back tomorrow and its same... i stop for 1 week i came back after 1 week i have 2 good games and then again happens that 5+ games with those people. My honor lvl is 2 im not negative,not toxic, not salty, not anything bad, in fact im really good guy, when i have time to chat i try to teach people and tell them where they make mistakes, some of them thank me for advice after game but 80% consider it as flame and report me, i really dont know how to make this community better, i think i deserve atleast normal ranked matches with same skill people. If anyone has anything good to say or advice me or anyone who is above us (players) in this system, community, please read what i wrote and please put me in better matchmaking, saying again, my mmr shouldn't be bad because im 10 wins over defeats. Thank you for your time. Greetings!
