I know how painful it's to witnessed such thing, but I would want to know if you have also tried using bc.game these while? Most times if your kyc details aren't that validated it could to account restrictions meaning all your details needs to reflect with each without any errors, and while doing verification there should be proper light showing your documents 4 edges clearly without reflection through the document.
The KYC was validated to level 2 prior to my making a deposit. I made sure of this. They retracted it after the deposit and stole the money.
This is said but I don't know how well they have made effort to resolved this, because if your details were verified to the level you mentioned and your funds where stolen it shows no atom of transparency, but however I have always seen stake to be a trusted and reliable gambling site.
