Today started with getting bombarded with robocallers on my Xfinity (non-landline) internet voice phone. I tried to register for Nomorobo through Xfinity website, but it asked me to put in a number to advance my phone number to, and then tried to test it. It kept saying "Your phone number is NOT protected by Nomorobo." I tried to call Comcast for help. Comcast's roboanswerers keep saying, "Sorry, there is a voice outage in your area." Really? That's odd. Then HOW COME I CAN USE MY PHONE TO CALL YOU? All I want to know is WHY ISN'T MY PHONE NUMBER SECURE? And as a side note, why is it when I browse the internet now, every 4th search results in DNS ERROR? How do I get through to comcast customer service?
