I did have to provide proof I was the owner of the account to get back in. I had a recovery email set though.
Then something not correct here. Did I miss anything to understand this issue?
What kind of documents do they ask to prove your ownership?
Why do they need you to prove your the owner of the account and when you already set a recovery email? It is very simply you request for a password reset and recover back your account from your email.
Basically these questions are asked while recovering accounts or unlocking them :
What is the username you want to recover?
What country did you most recently log into your Primedice account from?
What state/region did you most recently log into your Primedice account from?
What ISP (Internet Service Provider) did you most recently log into your Primedice account from?
What is your current public IP address? (you can find this on Google Search engine)
What is your deposit address?
What email is connected to this account?
What email is connected to this account?
Have you sent or received any tips from other account, and if so, please, tell us the usernames?
Have you referred any players to our site and do you have affiliate commission on your account; if you have - let us know what amount you got so far from the commission?
Apart from this a signed message from your address which you used to deposit will also act as a very solid proof.
