Game Won't Start

I just recently tried to start a game of league of legends. I had to wait 20 minutes due to leaver busters which were given to me for going afk for about 5 minutes, but that's another story. (My ISP sucks, I'm sorry) The game started and it went to a black screen. Now this was normal considering this was the same bug that has been happening for a while. I pressed cancel when the option came up and clicked play again. However this time, it didn't work. I tried this about 8 times before mid way loading in, an error message popped up saying, "The game is no longer available." And to my horror i was booted back into the end game lobby and was given 5 more leaver busters due to this shitty client not letting me join the game. This is seriously annoying and you need to get this fixed. I'm pretty sure it has something to do with the new patch as this has only started happening to me today, but regardless I now have to wait 100 MORE minutes and I lost my hard earned LP. If anyone has found a fix so that this won't happen to me anymore in the future, it would be greatly appreciated.
