I am Husnain from the account on EU NORDIC & EAST and my account is iAmHusnain.
Today Monday 16th April 2018, I had a match and I played the role as ADC and I was Kai'sa and in the match I have got my first Pentakill in my life and I was too happy. My friend had to go soon so we done a match and we lost. I decided to record my Pentakill but suddenly I have received a message on my LoL client saying I got banned. I got shocked didn't know what I did wrong then I re-logged to see that it was false or it was a prank or something but it was real and it was saying I was abusive. I wasn't abusive at all I only tried to help the team and my support couldn't play good so I have got a bit angry but I wasn't that much abusive to him I only said he is Trash and he was 0 at the early game that wasn't abusive.
Here the links about my ban and chatlog:
