Locked out of my hotmail account.

I've talked to CSR on Chat and via phone. I've submitted multiple recovery forms and still no success. The following is the message I received when I tried to login 'It looks like someone else might be using your account  To help you—and only you—get back into s**********@hotmail.com, we need to verify that it's yours.'

I'm getting more and more irritated because it shouldn't be so difficult and annoying to retrieve my account, that's the purpose of security questions and alternate emails. Please help me to login to my account its my personal and professional email account...I refuse to create another account

How can I retrieve access to my account?
