Why did i get leaverbuster?

Kinda wanna rip the hair outa my head thanks to the current games that i have played, but one of them took the prize and nearly made me do it. So i started playing another match, and for some weird reason i couldnt see the spells that i cast, so i thought okay that was weird, hope it would go away in a few secs, but that didnt happen at all, instead, i couldnt see my AA when i hit a champ/minion, and also i couldnt see anyone elses spells or AA, i kept dying to this little grahpic problem, so after my first death, i left THE GAME, then exited, then came back and it didnt change, instead, it said i got a corrupted file during installing/during patch 5.15, then after the repairs were finished, i logged in, and got a lovely leaverbuster notice.

Can you be able to remove leaverbuster off of my account? This is clearly not my fault at all. Pretty much your mess up, not mine.
