I don't know why there are a lot of complaints about Stake casino from some users lately, and I also question whether your complaint is true or not, so you need to provide evidence as a capital of your argument that deserves to be accounted for here, maybe provide screenshots of your gambling history, communication with the service, or your transaction history with the casino.
And it would be better for you to report on the Stake.com thread directly to get a response from stake representatives here rather than opening a new thread here.
