No longer have access to email account that “verify your email” code was sent to

I've got the same issue - no access to the email that the code is being sent to, and completely unable to reach any live agent through chat.  I don't mind making a phone call for this, but what number should be called and what issue should be given?  I tried to reach a live agent via the Virtual Assistant but the virtual just keeps saying 'tell me what your problem is so I can get you to the right person' and regardless of what I type, the same response is given.  

Thanks - I did call the 800-Xfinity number and tried to ask for Network Security - the automatic menu prompts didn't like that option and eventually said 'we cannot help' and hung up on me.  I turned to Google and found another number for Customer Security Assurance (888-565-4329) and tried their...was connected quickly to a great tech who knew exactly how to fix it and within minutes, I had regained access to the email.  Not sure why the bot assistant doesn't give that number out (or even recognize email issues as a problem to provide at least some resolution to) but right now, happy to have regained access.
