Riot please you are wasting my time

I got a leaverbuster cause I couldnt enter my ARAM game... and this is very un fair ..I managed to enter but i did so very late and we ended up losing .. I received a leaverbuster.. ALso my friendlist is not shown ..i have to restart the client multiple times. I want my leaverbuster removed and to think I was gonna spend mymoney buying a bundle ...on a broken game where i get punished for no absolute reason
