I have been unable to make a phone call using my home phone for 4 mos. Contacted Comcast (on my reliable AT&T cell phone) and Comcast said I needed a new cable modem.installed it, still did not work. Then they sent a tech. Made things worse, now no outgoing, incoming and TV problems. Tech was supposed to return the next week and never showed up. The final straw was this weekend when the bombings took place in Paris. My son is there as a West Point student studying abroad, and he was unable to contact me using the home phone, while my cell was charging. This is unacceptable as we also do not have 911 service. I have had Comcast service for more than 15 years with an average monthly bill of $275 and expect functional service.
