Unacceptable Customer Service.

On October 29 my next door neighbor was getting their cable service installed. While the tech was there my modem went offline. I ask if he disconnected my drop, he said no and that the signal was low in the area and a service tech was on the way. No on ever came and my internet stayed offline. I made an appoint for the 10/30 at 4:00. I was waiting at home when I get a text at 4:10 that the tech has arrived and should greet them. At the time of the text I was sweeping up leaves from in front of my house. There was no tech there. My Ring camera shows me in from of my house.  At 4:20 I get a text saying "Sorry we missed you today." No on ever came so l called Xfinity. They said I don't know what happened, but we will send out a tech on Sunday 11/1 between 4-6PM. I worked as a service tech supervisor in Philadelphia for 4 years and would never allow something like this to happen. The more we subscribers pay for service the less customer service we get. So now I will be 4 days without service because a Comcast technician did not care to do their job.
