How do I get access to my email if answering the survey with pasword reset request?

I had two email accounts that were linked. When one account had "security problems" and password reset wouldn't work I continued to access it by way of the other account. When account linking was ended I lost all access to my personal email account. In spite of every effort I have made to fill out the confidentiality surveys I get no where. How can I regain access to my own email account?
