A screenshot showing a chat to live support that still doesn’t have any response doesn’t make sense since your message is unread which means they are not ignoring but rather they just didn't see your chat because it's noticeable that they made a reply to you based on last conversation available on your screenshot.
Sometimes chat messages, support tickets will be stuck as backlogs and need time to be bumped or resolved. If it is in backlogs, it will need more time than usual to be seen and resolved by responsible staffs. Unseen means the user needs to wait patiently or bump it again. It does not mean the casino ignores the message.
How long does your email still not unanswered? You already post this on your scam accusation so it's better to discuss this matter there since Duelbits already replied to your issue on that thread.
I read that reply too and it is frank. The account is under investigation from Duelbits team and need cooperation from the user. I am not sure did the user cooperate with the team and submit required information?
I understand the frustration since there's huge money involved but casino investigation usually took a long time. Do you report this already on Curacao because they can help you if you really feel that you didn't violate their ToS.
With a big site like Duelbits, they can proceed that amount and they stated it clearly in that reply too. It's just they need to verify things carefully before proceeding it.
