Almost one year has passed and you still haven't received your money? That's crazy. I think that you should open a thread in Scam Accusation, provide proofs there too and ask DT members to tag Stake. If they get tagged, they might awake and come here to respond you and solve your problem.
The most terrible thing is that these casinos don't hire good employees. They treat everyone around the world in the same way. For example, I can't provide house bills or utility bills because in my country things work absolutely differently, you can't get any document if you live in a rent because it's unregulated, I can't provide utility bills because I pay it online via my personal number but these casinos don't care about that. They should hire people who know how things work in countries where these casinos run business. They should understand that every country is different and they have to know what they should demand from people from different countries. They can't ask me and someone from the USA the same documents because things work differently in both countries.
