I depositted ~0.057 BTC from Tor browser. And I bet all in %49.95, and win (0.1...).
After that, I've tried to withdraw. It has been pending for a while. Then it got cancelled itself, and I didn't get my bitcoins back.
I wrote to contact (yes I added email address), and after few hours they deleted my account. I can't provide evidences as they have closed my account.
Be aware!
You absolutely have zero evidences ? How are we suppose to believe whatever you're saying ? It all happened in span of a few minutes that you didn't have time to take screenshots of any ? You could have the tx of deposit made from the Tor browser to an address associated with 999dice ? Please update with more information (posting in their official thread on bitcointalk should help).
