Constantly Put with Rude Teams [+ Poll]

Lately, I've been constantly stuck with rude teammates almost every game. For a recent example, I was trying out the new champ select and one person said in chat that they were banning gnar because I had selected him to play (and they did indeed ban him), and to go with this 2 of my other teammates were completely rude for the entirety of the game, and then to add to it I never got a gank from my team when I had asked for help numerous times(I was 0/0 but I was struggling to maintain that) and even after I was being camped by every enemy lane I was still never ganked and my team didn't ever help me in general. There have been a lot of games like this for me and I'm not sure why, but it's starting ruin the game for me because it's rather difficult to have fun when you are constantly stuck with teams that don't help you or are blatantly rude to you. I don't play league near as much as I used to, so I was wondering if anyone else was having this same problem of constantly being put with rude teammates. (I know this isn't really a new issue but I haven't had so many games in a row with teammates as rude as they've been until lately)
