Needing access to my hotmail account that was linked to my sbcglobal account but no longer appears to be

I moved and switched passwords several times. My hotmail account was linked to my sbcglobal account so I do not understand why you won't send me a way to change my password. I am sure it is completely bogged down with tons of old emails and junk mail. I want to clean most of that out and begin using it again....but you will not give me access. How do I get around this????? I tried to reach out to Microsoft in the past and got the question "What is your favorite book". As a non-book reader, I cannot imagine what I would have used as an answer and certainly, I would have chosen another question to answer for security reasons, if that were possible. Can you not send me something through my sbcglobal account to access my hotmail account? Thank you!
