Am really sorry for you loss I would like to advice you few things to consider:
Please try and file a Public Interest Ligation against the casino since this would help them take this matter a bit seriously.
The owner is offline as well therefore I do not think that you can actually expect much as well. It is not really a big matter, the casino is moreover*might be a scam, might not be a scam*
Please reach out to other people on the forum as well to help them change their reviews, of the casino as well.
Here I found a lot of useful tips from really knowledgeable and experienced people, thank you!!! I found several sites where I also left a review and now I'm waiting for what all this will lead to. Thank you for your concern about my problem! It's very nice to see that people are trying to help each other. You don't know me at all as a person, but you gave me so much advice and support!!!
Guys from the Bitcointalk forum! I can't put into words what just happened. After two months of endless nerves and worries, I was finally contacted and my money was returned!!! I have no words to thank you properly. I'm new here, but you treated me patiently and kindly and helped solve my problem!!! I'm immensely happy that justice has prevailed and I'm grateful to those who decided to show compassion and patience. From now on, I'll always read reviews about casinos before playing there (as I was advised by many here) and I'll carefully approach the choice of a casino. Thank you all!!!
