Why are solo queuer being punish all season

target banned me as a quad queue and attempt to set me back as much as possible during the game. Really sad game as a solo queuer going up against literally 9 people who has a main goal of trying to attack me. I am unable to say anything at all because they all would just attack me all together in team chat and all chat in which I have absolutely 0 voice. I just want to try to hit diamond for once and being set back this time and time again just because of this system that has been going on the whole season is real painful to go through every day as I hit to queue up alone.
