I fear that the player that sabotaged my match from champion select won't be banned.

I've been on a 10+ game winstreak and its recently come to an end 2 games ago. I won the next match and was at 95lp from promos then in this most recent match I had a troll.

From champion select he banned my champion, he was my support bard. He said that my champion was op and he didn't think I was first pick to grab her. I was pissed but believed him and picked tristana. Seconds before the match started he takes smite. At the start of the game he takes our Rammus's red buff we leashed him by smiting it. With the red buff and his abilities he starts trying to take all my cs and never put down a single heal when I got low. When the enemies backed he kept trying to deny my cs with his Q and his red buff (which he stole twice) and ulted me to keep me from getting cs. I have 46 cs compared to caitlyns 100+. I was pretty much usless the whole game, the only thing he did was go around stealing kills and taking cs so it looks like he wasnt trolling.

I'm afraid he wont get banned because the stats don't look like he was trolling and makes me more look like I was a bad adc. But if you look at my match history this match is very out of the ordinary compared to my performance in the past 10 games. I wish I could reveal his username so you guys can report him but sadly I can't. I hope this player gets what he deserves. Our team reported after the match and I wrote a ticket. This player needs to get banned.
