I just know this, that BETBTC closed, I never got email from BETBTC team that they are closing, now I can't even withdrawal, which site sudden close and give ony 15 days to withdrawal and no email from team....
I can still access the website, but if the withdrawal period is already over, maybe you can send them a PM, and who knows they'll process your withdrawal. Their forum account is still active, so message them and hopefully they'll be able to address your problem.
