I have never had such a bad experience with a business. For a week I have called the NTTA number and it has been constantly busy. One time a recording answered to say they were busy and then hung up. I also emailed the NTTA my questions a week ago, and again, no response. How is it that this agency can operate this way? I am going to have to drive to the Plano location just to try to get an answer. Not acceptable.
