Could you help me?

Hi, I'm French, so I try to explain my problem on NA forum, if I make some mistake, please, forgive me. I had an accident few months ago, i couldn't leave my bedroom during some months and I played a lot to LoL, this game allowed me not to fall in depression, but you know, when you stay few months at your home, you become a bit different, i became a bit salty, but not toxic. I recieved a 14 day ban, i'll not explain the logs, guys teased me, i answered, it's MY BAD, i know it. I sent X messages to support to be a better player cause i've done my exams and got this ban in the same (1 week) time, i decided to change. I did sport again, i became nice, I always wanted to help everybody in my life or in this game. I changed, in 1 week, i've done between 40 and 60 games (it's a lot!) and when I had a problem, an instalocker, flamer, I reported and sent a mail to Support, to know "how to react in this situation?" but he didn't help me, it was recorded answer. I sent mail everytime when i had a problem, i wanted to change, i didn't flame, i muted, i've done everything i could. I remember, one game made me sad, a guy instalocked, for my team i went support and they flamed me, i couldn't answer so they made me sad. And I decided to help people in the same situation, a Gnar 0/13 has been flame by the jungle and the adc, i defended him less flame, i asked to stop, to keep calm, i said i didn't want to report them, i muted but i dismuted cause gnar was alone against this 2 flamer. Just after the game i sent a mail to the support (again) i said I've been probably reported by the jungler and the adc (extremely toxic) and I didn't want to be ban cause i've done anything, i sent the message and saw a new mail "you've been permanently banned" ... My logs are on my french forum (comment). I fight since one month to recover my account but nobody read the logs. Forum support me, some rioter support me, 1 ex rioter support me but all of them said "contact support" and support doesn't help me. I'm not an angel but i tried to be, maybe i burned my wings cause I tried to be near from the sun... Thank you for reading.
