I'm getting booted from games at an unbelievable rate

I'm experiencing this bug where I get to the end of Champion Select where I lock in my Champion, the count down hits zero, and then I never go to load in screen. Like, I am just sitting there in the home screen of my client with everything blanked out except the words "Game is still in progress." Basically the game boots me after champion select and I am not given the choice to rejoin.

The fact that this ever happens is bad enough. People get banned for dodging. But this is happening 3 times for every game that I actually get into. Not even kidding. For every four Champion Selects that I finish I get booted out of the game three times.

You'd figure that Riot, a company that gets paid because people play their game and thus choose to buy RP, Skins, Chroma's, and the likes would want you to be able to play their game. So that you buy more RP, Skins, and Chroma's, but no. Instead, they let critical errors occur for weeks on end that could be fixed by any Sophomore Computer Technology major in a couple days.

I may just have to quit now. I basically can't get into games anymore. So, what's the point of trying?
