they did not give any reason, this company is a scam, all players should be warned to stay away from these cheaters.
of course they demanded a selfie with a card and the words cyber.bet. but I sent everything they wanted because the account is for my real data, I don't have multi-accounts, only on this account I made deposits and received the bonus.
Sorry about what happened to you, Well @Cyber.Bet and the only available support of this casino on the forum was last online July 07 and they did not even sent one post in the thread providing that was about scam accusation against them, and that proves the whole website is probably a trap to attract some users into using their casino website by promising bonuses, and then if they want to withdraw delay the process by asking for ID, there's even a screenshot of them in that topic that support asks the user for Skype verification after the user completed KYC process which says a lot.
