Maestro error and my Rank

Its already hard enough to climb for me and now I am getting Maestro errors, which closes my game in the middle of champ select. Happens 3 or 4 times per day, 5/20 mins bans from q thanks to that and dont mention the -3 lp u get every time this happens. I am writing this in hopes a riot employee can read this. This game has the most irritable errors and annoying ppl. Im seriously quitting, give my money back.
