How do you get Xfinity/Comcast to come out and clean up old cut and hanging cables that are in trees?

I just moved and my new house has a couple of trees and a utility pole and the end of my driveway.  There are literally dozens of Comcast cable lines hanging in my trees, all appear to be cut an unused, and a rats nest of old wiring on the utility pole.  I have made several appointments for someone to come out and take care of it, but they've never shown up.  I am no longer an Xfinity customer, and have no interest in getting service in my home if it's just going to add to the mess that I, and my neighbors, have to look at every single day.  I'm tempted to get a ladder and some wire cutters and just do it myself.  Can someone at Xfinity please contact me to address it.
