Internet Installation at New Address

I've got a unique issue. I'm building a house on a private road(i.e. driveway) 700 feet off of a county highway. The issue is our new address, assigned by the county 911 office, does not show up on any of AT&T's maps/databases, so they are refusing to send a technician out to even investigate the possibility of telephone/internet options available. Both of our next door neighbors have AT&T DSL internet and telephone. One day, an AT&T technician named Joe Horton was working on one of my neighbors boxes. I stopped and asked him about the possibility of telephone/internet at my new house and he took a minute and looked and told me the lines were available at the county highway, and should be available to my house. How can I get AT&T to send a technician out to investigate, and install telephone/internet? I would appreciate any assistance.
