HUGE BUG

When the Servers just crashed, I was given a LEAVE while my buddy who was in the SAME GAME was given a win... ( we were clearly winning the game was why im assuming) ... I was in my promo for plat and that made me lose my promo.... If there is anything anyone at riot can do to remedy this situation, I would be greatly appreciative.... ive spent way to much money on this game for some bull like this to happen.. come on guys!
