Account Suspended for 100 years

As you can see my account was permanently banned for the list of reasons above but some of the things listed on their reply to my ticket is stuff i would've done months ago and a few things I've never even done. They state that I've chosen agents in order to throw on purpose which i can say i have never done and also feeding the enemy team which would arguably just be an aggressive play style. The only warning i got for this ban was for AFK/leaving games when i got frustrated or even my PC/internet crashing. I wasn't warned about a possible permanent ban or about the bad behavior like throwing etc, just that around a week and a bit ago i left my game on purpose as i was frustrated (this is on me 100%) i had no idea leaving one more match or even my internet crashing after that would result in a permanent ban and riot throwing in all these extra reasons that never even occurred to me. PS: i was never a thrower exactly i just used to play like i didn't care about the win but still focusing on winning each round. I also do admit the typing in chat where my team was positioned was fully on me and i did know it was wrong, it was quite a while ago and i was never warned on my behavior of that. Just wondering if there is any other way to appeal because they've decided to instantly close any more tickets they get about it. It seems to me as they have dumped all the bad things I've done in one fell swoop to perma ban my account.
