I want to double down upon what you are saying as you know far better than the parent what is going on.
Just today I had sub-sub contractors from Comcast trying to fix the cable from the box across the street to my home for an issue I first reported the issue in mid-December but after a few months of nonsense things finally got worked out.
After first having a visit from a person who appeared to be a Comcast employee declaring the connection between my home and the distribution box across the street bad (I was seeing
A week later received a note from a sub-contractor of Comcast (though with the Comcast letterhead on the door hanger and the sub-contractors name in the fine print) which said my cable needed to be replaced. Over the next couple of months I'd call them to check on the status with the work order # on the tag as things slowly worked their way through the Comcast and local city bureaucracies.
Eventually they told me that the work had been issued to a 'sub-contractor' (really a sub-sub-contractor) who took about a month to get things worked out as well between the city and them (which included two paintings of the paths of various utility lines under and around the street (much to the annoyance of the neighbors who didn't like the paint on their property)).
Finally the day of repair arrived (today) and they did their digging... alas they hit a rock when tunneling under the driveway of the neighbor in front of me (and right next to the distribution box) so they had to fill in most of what they did (amazingly professional in this way) and say that another team from the same company would have to come out in a week with a different boring machine to complete the work.
The pathetic thing about this whole process was that as far as Comcast is concerned, my issue has been resolved months ago by virtue of it being sent to an outside vendor... in the close out email even citing the fact that my signal strength had returned to normal (hint: it hadn't fully).
There is a part of me that is considering dropping Comcast service once this whole repair effort is complete (costing them $5-10k)... however they (unfortunately) provide the fastest internet for the price... when it works.
