Actually, You look more a clown here rather that Duelbits that you are criticizing. You are already updated about the ongoing review on your account while you are accusing them that they are scam. Your proof show that you use Duelbits few months ago without a problem.
We don’t care about your PnL or bankroll. You are accusing a reputable casino as scam just to speed the process of your case while they are answering to all your inquiries. You are reacting as if they are completely ignoring you.
OP is in a hurry to accuse if they denied your payout then that's the time that you can call them scammers or post a scam alert but if you're that serious about making a mess out of Duelbits then move this thread in the scam accusation and follow the right format, the representative will address your concern, but this is going to be a long wait if you act that way, be civil and request to fast track your request.
We are talking of half a million here I'm sure many will follow the updates here and they will probably like to fast-tract this issue.
