The main problem is that they do not accept the document issued by the company
The electricity and water document that comes to the home address, is photographed and sent for verify and that document stake.com rejects
What now? Let's create the impossible I don't understand? really
Of which... I tried to figure out. Given Stake is one of the few casinos that doesn't give me their contact, I can't reach them directly to hear the story from their side. Thus, all I can do is to help guide your steps toward resolution. As mentioned by severals, you can go to CG or AG and get the mediator to resolve the matters, get Stake to explain why the documents are rejected.
Or... you can help me understand what happened here by answering my previous question, whether it's you or your cousin who try to verify. With that, I can advance and probably understand where the issue lies.
