Lost 50 LP from remake because of leagues client

I was getting into a ranked game with my duo partner, when it crashed. Usually, the reconnect button appears, but this time it didn't. It never came up. Even after my friend got into the game, I couldn't reconnect. I restarted the client several times, and nothing happened, still no reconnect happened and it said I was in the game. This continued till the remake happened, and there were apparently 5 votes available on the remake, which means the client and game thought I was in the game, even though I wasn't. This means that Riot's client, which didn't allow me to reconnect, then in turn penalized me. The screenshot I sent is what I kept seeing every time I re opened the client. Nothing I could've done, and yet I get penalized and punished for it. I got leaver buster, which is absolutely absurd. I have not afk'd or left for years, and this is the first time, and it was due to this bug, and I get leaverbuster? I'm so lost and confused and annoyed it makes me not want to chance it anymore. This is one of the most irritating things I've experienced with league of legends in the 2 years i've been playing it.
