Unable to Access Xfinity Voice Site

To note, my home phone service is working fine, in that I can make and receive calls without any issues, my issue is that I cannot access the Xfinity voice site.  

For troubleshooting steps I have already done, or verified, with Xfinity support (via Reddit) includes:
1. Confirming that I am not using a VPN
2. Confirming that I am logged into Xfinity as the primary account (ronald.scheff) that should have access/permissions to the Xfinity voice site
3. Tried clearing my browser's cache and cookies
4. Tried accessing the Xfinity voice site using three different browsers including Google Chrome, Mozilla Firefox, and Microsoft Edge
5. Tried accessing the Xfinity voice site on completely different computers, using the same browsers including Google Chrome, Mozilla Firefox, and Microsoft Edge

No matter what I seem to do, I am unable to access the Xfinity voice site using my account.

Support from Reddit mentioned that I need assistance from the "advanced team" to look into this further. 

Thank you.
