Banned - no reason

I was banned from league for the first time in 6 years of playing at the diamond level. I was reported by a player named 'toxic'. I was banned for a full 14 days from this. I had the most damage to objectives, the earned us the first drake, first kill, and first tower, and the rift hearld as a jungler. I was playing with a duo it was a 40 minute game that we lost and I apparently had a ban-worthy presentation although i played very strong and generally do not talk much in game.
