To be frankly speaking, the chances of you hearing anything from this scam casino is very slim, because had it been they had the intention of doing so they would have done it publicly rather than choosing the PM method, to prove they are no longer a scam caseino everybody know 1xbit to be. So my friend, I will likely advice you, please just stop wasting your time, but if you wish to give it a try, continue..
Though almost no chance of getting the dollars still s/he should continue contact with them. They may release funds if that is a small amount and at the same time if they never solve the problem yet other users will be able to save funds as the topic may show them first which will prevent them from being scammed.
