New Construction Service

I have a new construction home that i am building.  I cannot seem to get anywhere with getting a new cable run from the pole to my house so i can have service.  The name of the road name  changed a few years back due to anexation and it is causing all kinds of problems.  Comcast reps are telling us it is not servicable, but the house right next door has had service in the past and the house two doors down has service now.  Of course their service is listed under the old road name so when Reps search for the current road name they don't see any subscribers. Any suggestions on getting someone out to lay eyes on the situation?
