Need help removing old cables/wires from home and pole

We just purchased a home and there are 2 cable lines running from the pole into our yard, they have already been cut from the house by the previous homeowners but the cables were left running through a tree and now are just dangling from the tree into our yard and still attached to the pole. We also have a box labeled "Xfinity" attached to the side of our house with an orange cable running from it and going underground. I am trying to get all of this removed, as we do not need them and it is limiting our ability to do needed maintenance and yard work.

I have tried to get in touch with someone over the phone, and when I do, I never get a follow up and this issue keeps going unresolved. I am not a current customer and have never used Xfinity/Comcast, so I understand that it makes my request much more difficult to track.

If this is something that I could get help with, it would be very appreciated!

Thanks in advance!!
