Just to update. We have not regained access of the domain yet, our registrar has been slow at responding but there are a lot of people on our side giving us a hand and we're confident access will be restored promptly.
Thanks to everyone here rapidly spreading the word and recognizing something was off on the phishing site, the person responsible only managed to earn 0.05BTC and we already have a solid lead into who it was and how it was done.
Important for me to stress that you cannot trust emails from @primedice domain at this time. They have setup a mailserver and we have rotated emails off any accounts that use to use a PD email.
