I have already sent a message to one of their account called "8bet" two days ago. No reply. Their other account "8betnews" can't receive messages from newbie.
8Bet is supposed to be their personal representative on this forum but his last post was on the 10th of January and he didn't login here for more than 3 months. If he didn't log in he can't read your pm.
8betnews is a bot used to post updates and notifications about promotions and contests. He doesn't even reply to members' comments in their official thread. Don't waste your time trying to message him.
