“It looks like someone else might be using your account To help you—and only you—get back into ******@hotmail.com, we need to verify that it’s yours.”

I received this error message when trying to access my email. I have filled out the account recovery forms multiple times and have received no help. I have called microsoft at least 5x and have created a case #, however, they keep direction to fill out the account recovery or reset password forms online. However, the online account recovery and password reset do not help as whoever hacked into my account has changed information such as security questions and recovery email address. I need access to this account immediately. I have been trying to gain access and support for a week now.
