Trying to contact construction/maintenance division to get a cable buried

I've been waiting for 33 days to have a cable buried. The cable is already running from the box at the street to my house. I got an email saying a team had been scheduled to complete the work, and that it would take place on 6/17/24. It didn't.

• When I called 800-XFINITY on the morning of the 17th to try to find out what time the "team" would be at my house, I was told 1:00.
  • At 1:50 I called and was told "in the next hour or two."
  • At 4:30 I called and was told that I would receive a call from the construction department within 24 hours.
• Today (the 19th, 36 hours later) I called and heard
  • (a) construction has no customer contact;
  • (b) customer service has no way to interface with them;
  • (c) I somehow would usually hear from construction within 48 hours of some unspecified time (I assume the time my issue was escalated on the afternoon of the 17th); and
  • (d) would I like to save on my plan with this sales pitch.

I just need this line buried, and I would like to talk to someone who actually knows things like when that's going to happen. How do I do this (not that I should have to)?
