No service at address but made an account? can i get service extended roughly 700-1000 feet from closest service

I went online and got service account, I explained online that i had attempted to get service back in 2014 and they said i was NOT serviceable then. The rep assured me that i was in a serviceable area now and that it could be installed as soon as a couple days away. Since then i have had 3 techs come out and tell me the same thing. I had to pay for a plant extension since there was no service at my poles. The online chat assistant wasted my time for 3 appts, and an hour long phone call for them to tell me that i needed to walk in to a local branch and see WHEN they would have service at my address. The in-store rep said he opened a ticket and to check back in 10-14 days. Its been over 10 years with ATT at 100mbps service. I really want something faster that can handle more traffic.
