I used to be a squatter in New York's East Village. I moved from one squat, where I had a phone, to another a couple blocks away and had trouble getting the phone company to install a phone in the new squat. So I ran a twisted pair through back yards and vacant lots, across a pair of diagonally opposed traffic lights at an intersection, along the face of a building under renovation, more lots/backyards, etc. It worked. I had to repair cuts in the line a few times. Eventually the phone company gave me a new line. Maybe you should take things into your own hands.
