Some interesting info from @holydarkness
Info 1)Stake scans this board!
Though they barely address matters here, this board is routinely scanned by one of their representative who then forward the matter to their complaint team. So, quite likely, their team has been made aware of this thread. Hopefully, they can overturn what "can't be overturn" by their live support.
Info 2)Info 2)
If you did nothing wrong, Casino Guru will make a ruling Stake will follow!
Otherwise, as you've escalate to CG, and if you did nothing wrong, you can rest assured that CG will find and made a ruling that Stake's decision is unacordingly, and most likely than not, Stake will comply to CG's ruling.
Wait, Casino Guru closed my complaint about Stake's provably rigged in-house Black Jack!
