Bans

Recently I was hit with a temp ban (15 days) over a bit of dark humor that riot took harshly, but that not why i'm here. I'm here because I was wondering if someone were to be perma-banned if any of the money they have spent on the game is comepletely gone, or if they can get it back somehow because Ive spent more money then im willing to admit on this game haha if anyone knows let me know (I'm not asking because I think i might get Perma-banned im just wondering
