Restore blocked account!

Can anyone from Microsoft help restore my wifes account? Tried to restore it by sending out the restore form, but every time it came back as insufficient info, and no other help options available...(and we not even sure if the details submitted were correct, because she used it for so long she cant even remember all the details!) so now the only option is a new ACCOUNT , but she doesn't need a new account, she needs access to her old one! Is there anything else she could do? I mean what would it take to gain access back to the account?:- phone? pasport copy? blood type?  There must be something that can be done! anyone could contact me to talk?  Microsoft takes security so seriously that even the owner can't access it's own account! ........
