Should be titled "Scamming back my scammed account that was scammed," technically. As in, you scammed an account, then that got scammed, and you want to scam it back again, so it's kind of a triple scam.
Anyway, first off, are you US or EU?
If it's US, you need the first name, last name, and secret question/answer of the account to get it back. That's it.
It appears you don't have the first and last name, so there is nothing you can do. =/
