Since Microsoft unlinked my email accounts I cannot get into one of them.

I am not happy about the unlinking of Microsoft accounts.  I have three email accounts for three different purposes.  The linking of them was great for me.  Now that Microsoft unlinked them, I can only access two of the three.  I have tried to reset my password.  I have answered my security question but it doesn't accept the answer. I have fill out the resulting form, many times, and I get an email telling me that the computer did not have enough information to verify my account.  This is frustrating! I need to access my mail! Is there any other way to get into my account? Can I talk to some one human and understandable to help me get my account back?

Thank you for your time.
