A seller on U7BUY loaded too many Clash of Clans Gems onto my account and then threatened me to transfer money to him or he would have me banned from Clash of Clans. I didn't believe him, thought he just wanted my money but he made it happen. I now have minus 22500 CoC Gems and can no longer buy anything in the game, my account is effectively unplayable for me and all because of a seller on U7BUY who betrayed and reported me on Clash of Clans for the Gems I bought on U7BUY, i.e. from him. I reported the whole thing to U7BUY about 7 weeks ago and to this day I have not received any compensation and the seller has not been punished for this behaviour. UNBELIEVABLE! Never again U7BUY! Very dubious platform.
