Account hacked, tried all recovery methods!

I have been trying to acces my account (removed) for a while now and i always get the same answer when i try recovery: 

We recently received a request to restore Microsoft account (removed). Unfortunately, our automated system determined that the information you provided is not sufficient to verify that it is you who is the holder of this account. Our customers security and privacy are important to Microsoft, and it is imperative for us to do our best to protect your personal information. We have taken further action and blocked your account until we can verify that you are the proprietor. This prevents the account can be used again and protect you from malicious activity on the account.

Which brings me to my next problem. I made this account when I was 9 and i dont remember what i filled in becuse i was I 9. The account that's been compromised is linked to my Battle.net account, which I've recently found out has also been compromised.  When I tried to log into the game World of Warcraft, my password was no longer recognized and someone had added an authenticator to my account which hadn't been there previously.  Blizzard's forums have been blowing up regarding hijacked accounts, usually by Chinese players, who steal the player's money and gear and then sell it for either in-game currency or real life currency.  Thus I can assume that there is a direct link between my Battle.net account being compromised and my Windows Live account being compromised.

Please help me!
