Unluckiest Person Ever

I lost my first game fair and square, then I was in my Masters 0 lp game, so if I lost it I would demote. I came in ready to play the game. At 6 minutes, I get "Reconnecting" and I switch to my chrome tab and spam every possible link. Internet was working fine. Everything was working fine. I Alt + F4 and clicked reconnect. Black screen. I ran to my teammate's stream and started spamming that my game wouldn't open. I restarted computer, black screen again and said "can't connect to server." Eventually after 7-8 minutes worth of spamming reconnect, I decided to restart again. This time, it opened. I lost like 7-8 minutes worth of game play, but I came back and my team didn't flame so I kept my head in the game. After all, it was my demoting game from Masters to Diamond 1. Why on earth would I disconnect or give up ever? We played it out till 35 minutes and won. I was ecstatic I wouldn't lose diamond + gain lp. We won, I took a defeat -- clearly due to the inactivity (7-8 minutes due to client being troublesome out of 35???). It feels terrible. My internet was okay, I was trying so hard to win, and then due to the client completely crashing on me, I got a defeat AFTER winning a comeback game. I demoted and lost Masters. After spamming all season (even though it's preseason) to get it, I finally got it and I've been screaming my head off. I lost it due to a client bug.

Now D1 50lp. I sucked it up and played more games. I won two back to back. Win 17 lp each. I'm at 84, one more win till I get back to promos. Client freezes in champ select. I'm first pick. Summoner 1,2,3,4,5 is all I see. Can't pick champ. Gets kicked out of champ select -3 lp. Now 81 lp, can't get promos in 1 win. Now need 2, again due to Client.

So going (2 wins + 1 "loss" win) 3 Wins and 1 Loss + 1 forced dodge due to client, I went from Masters 14 lp to Diamond 1 81 lp literally due to client.

Is there literally any way to get this reverted? How is this fair at all?
