LeaverBuster for no Damn reason

So I've been playing LoL again and having a good ol time when I got leaverbuster for no reason after actually carrying my team and not being toxic/afk, once was meh then it happened again and a fucking again. Now I'm sitting at a 10 minute wait time to play this game and I'm pretty much fucking done, this is bullshit and you all need to get this shit fixed. I know I'm not the only one having this issue and I'm about to just get a lot of people to leave the game till you guys can get your shit under control.
