I have been playing at stake or have been around stake for whenever they started, I have been at the early days of primedice, I literally remember when primedice didn't existed, I have been around for that long. And I haven't seen a single time this team didn't paid anyone who actually played legitly.

Either there could be an issue or there could be some rule breaking and so forth because I have seen plenty of times back in the day when people decided to double spend method and failed because stake basically do not give you the money that you won illegally, they are quite good at that and many people complained and the real truth comes out. So, either your issue will be fixed as well if you really think you did nothing wrong don't worry about it, or its just another scammer.
