I have several low hanging utility lines coming off my house. I called Dominion about the power line but others look to be phone or something else lines. I do not even have a landline phone. How do I know which phone company would service this if I do not have an active landline? Any help is appreciated. Can the city come out and see if any of these are city lines? This is at 4003 Patterson Ave, lines come off back of house to telephone pole. There are even some loose and exposed wires on back of house.
