[WTB] Help getting back an old stolen account in WoW

[^^Miracle]

A long time ago (around 2 years I think since it was the end of the Cataclysm expansion) I tried to sell my WoW account to a guy and he scammed me, I gave him everything and he didn't provide any payment. I have tried to get my account back by 'legal'/blizzard means but they always keep asking for an ID but the account isn't on my own name registered, it's on another name so I can't give them any ID and they keep saying that all the info should be filled in truthfully and that account sharing isn't allowed etc... Also I can provide the following additional info for my account if someone is up for helping me out: old e-mail of the account, character names and servers they are/were on, codes of the games that I have bought and put on this account(vanilla, burning crusade, wotlk, cataclysm), name of the account(i don't know the battletag sadly), secret answer and also codes for the gametime cards I have used. So I'm asking is it possible to get my account back? Of course I will provide payment for this service. Please contact me by PM if someone is interested.
