You know, I can send Duelbits support a message everyday to remind them about my case and inform that I'm still alive and waiting for their judgment (I'm feel really like I'm in jail due to my stupid mistake and waiting for the judgment from the court, lol). But I think it's not a good way for my case, I don't want to make them feel annoyed and stop conversation with me forever. So I only do that once a week or once every other week. And during this long waiting periods, I feel better when I read all your comments.
They will feel intimated if you annoy them with messages every when there are a lot of issues coming in their support so it is just right that you don't message them every day once a week is good enough so the support will remember your case.
So much depends on how you configure your request, It should not be demanding or you feel that you are depressed because of the issue pressuring them to take action immediately, make your request light and sincere.
I believe that Duelbits will show compassion and goodwill and send you back your funds or credit your account, it will be in their favor if they resolve it, because the confidence of the gambling community will go to Duelbits for their goodwill.
