toxic brand

I was playing a game as kat and everything was fine, my friend (who was playing cait) was lagging and the brand decided to go beserk and not type the whole game until after it ended. he kept spamming ff the whole time every time it was possible to click and was constantly without the team. in the end we won with the help of every ones part but after the game he started to flame for abt 5 mins straight, i belive he was sent 3 reports by me my friend and possibly the gnar but the way he reacted was unacceptable and i want to make sure no one in the future recives him in another game just for him to start to flame and spam pings or ff every 4 mins, even tho we sent the reports i don't belive what happens after game can be seen, i forgot to copy it until after i left but would like to keep riot updated on a very toxic player that has not right to act the way he did. He also said the cait afk which was also incorrect, he was just lagging and got some things late which made the brand get pissed and ping cait every time he gets a chance to. Some of the things said by this guy were: "shitdog" "cait was afk" and mixing words up with bronze. I cant vividly remember every thing the brand said but he said far more worst things than this. and i forgot to copy what he said but i sent a report like i stated before and the way this brand acted is untolerented in the lol community.
