No service

There have been repeated outages in my area for the past 4 months, almost twice a week. They brought down the service again at 4:30 yesterday evening with an ETA of 6:30 PM. The service was reportedly back up at 8:30 PM but I have no service. Modem keeps blinking yellow. I was with the chat people for over 2 hrs since then. Initially they promised a tech out to me first thing in the AM. Later the chat was transferred to another and this guy says nothing is open until 08/29 10AM. I asked him to waitlist me for an earlier time slot, and he waitlists me for 08/29 12PM. I have the text to prove it. Where do they get these people from?

There was an Xfinity van in my neighborhood yesterday. Everything was fine until they showed up. Then the service goes down. Why can't they check if things are in order when they restore something? Why does a restored network outage not restore my service? Why can't we talk to someone, instead of dealing with the chat folks?
