Ban Appeal

So I've just been permanently banned out of nowhere. I was playing ARAM and was admittedly very salty and said a few things that i shouldnt have, nothing was aimed at anyone specifically it was just me venting my rage which isn't an excuse because other players for sure don't deserve to see that. I used to be a very toxic player and still am to an extent only now I just rarely talk to avoid creating drama and getting banned.

So I wasn't sure where to put this but I'd like to request an unban or instead of perm just 2 weeks or maybe a month. It has been a long time since I got banned or had an incident like this so I want to request one last chance, I'd really prefer not to have to do it all over again.
