Thank you a lot for the intention, but...
No, i am not able to retrieve any details, because this company (as we found out later) created an email for us, and this email was used by them to submit our initial DV form, and then provided us an invented confirmation number (more looks like an inventory number for their business than for our case). So we have no valid information except the name of the winner and of the dependents, date of birth, etc.
That website I posted is the US Travel Documents Customer Portal, it is an official site, our embassy created an account for us, and provided us the username and password to access it. It is the way of schedulling interviews for any type of visas.
Any way, I understood- we are a strange country
Meanwhile I checked the forums in my country, it seems the embassy will send all of us an email in 1-2 weeks from now...so waiting continues
