Help getting a security code

Having just spent 40 minutes on the phone to 3 diffrent Microsft support people, I have been told to post my issue on this forum and someone from Microsoft will help me.

When I try and log into my Microsoft Account, I get a message that says it looks like someone might be using your account.  So i click "next" and attempt to request a security code.  I have the option of text or email.  Text doesn't work as I input my landline and not mobile number when i set up the account, ut when I select email, it brings up an email message to say, the service is unavailable please try again later.

I have tried the third option to verify my account which requires a form to be filled in, but all I ge in response to this, is a password reset and when i try an log in, I still get stuck at the security code screen.

I an using IE and have tried diffrent computers, iPhone, Blackberry etc.

Any help is appreciated as I don't want to lose my xbox live gold membership and Gamertag by simply opening another account.

Thanks.
