Property Easement

Like many others, I am trying to communicate with Xfinity trying to find access to an easement Comcast claims they have on my property. I have gone through chat and provided my address information and asked for documentation, but all I get back is a question asking what services can I help you with. This is urgent as an adjoining property is trying to bore through my property to connect to the box at my house. Of course I cannot speak to a representative.  Thank you.
