Blocked account kindly un blocked

Hello,
I was out of town on business. When I returned I attempted to logon to my hotmail email account, and was greeted with the following message:
"Your account has been blocked
Why are you seeing this?
Someone may have used your account to send out a lot of junk messages (or something else that violates the Windows Live Terms of Service).
We're here to help you get your account back.
What do you need to do?
We'll walk you through a few steps to verify that you own the account, then have you change your password in case someone else has been accessing your account. It should only take a few minutes and then you'll be unblocked and on your way.
We've cleaned your account settings
Often customers get here because someone else has access to your account and are using it without your knowledge to send spam. To protect you and your contacts, we've removed any Hotmail auto-replies or linked accounts you may have had."
When I click on the "Continue" button it transfers me to a email address that has not existed for more than ten years. When I attempt to access that email address I receive a message that the email address does not exist.
I must access my email account, immediately. I have had no access now for nearly three weeks.
I have spent more than fifty hours on a wide variety of sites attempting to access my account, without success. I am ready to pull out my hair. I did not ask that my account be blocked, but it is.
I have telephoned MSN attempting to speak to a human being, without success.
Every route I attempt eventually cycles me back to the site that has the email address than has not been working, or utilized, for more than ten years.
