Ibracadabra

Hello, (sorry for my english) Because i don t know how to contact the support or someone that can help me, i decide to write here. So one player harceling me and i don t know why. Everytime he kick me, he join my games and tell the main player of the game to kick me. He tell every one to kick me.He spoils my pleasure of playing. i tried to understand why but he never want to say. So if someone can help me to contact a support or to understand what he hate me for no reason.
