I need to get someone banned, they ruined my ranked game and were very toxic

I just played a ranked game, and I had a blitzcrank as support. Throughout the whole game, he would not let off of caps, would not stop trolling, and even when i told him i was recording and sending the logs to riot, he continued ot troll my team and I. If anyone could help me bring this summoners account down, that'd be great.
