Banned for mmr boosting out of nowhere

I tried to login yesterday and i was cheered by a ban, I check my email and I was banned for mmr boosting, losing all my rewards that i earned playing over 1000 games in one single season... I went from tilting to the point of breaking my pc, to climbing unexpectedly fast... My countless hours of watching pro play reviews and reviewing mistakes was awarded by getting higher than my expectations and managing to make it to plat... getting that precious border and finally a victorious skin.I sent a ticket to no avail..

their response in essence was: there was a deep investigation/ punishment might feel harsh/ boosting ruins the spirit of the game...

I said a message telling them that i do realize they can’t disclose too much for obvious reasons, but i explained my grind... all i got was a generic response....

I played a lot of games, different moods and different periods and metas went by, in which i tried to adapt to... this so many champs played... the real climb for me was when i picked up jayce and got out of silver... then I started spamming games and trying to adjust to the meta.. but then I realized that that doesn’t work on those eli’s as much.. i spammed games but i got hardstuck, until i managed to get out of low gold, and i worked my way to plat.. i made it one win away from plat 3, but i came short... from that i went on to have a g5 mmr.. i tanked the season and got demoted in the preseason, where i got back to plat since i was playing with much lower mmr, but eventually i started feeding versus mid plat again... my play is inconsistent which forces me to pull out odd picks directly in ranked, and if they work out, then i spam them until i start underperforming.. then i go back to old mains only to repeat the cycle.. apparently my sudden climb was enough to be banned... i feel so let down and frustrated... this is so annoying to have spent so much on one goal and then lose it all like nothing, and staining my profile...

rito plz...
