Factory responce

I have sent 3 emails over the last two weeks to the factory asking for info about the new Rise . I will be in Tenn. next week and had hoped to go to the factory to see how they are built and review the product. I also called but got an answering machine. I did get an email saying that someone called . He did not answer any questions or give any advice. I tried to call but got a machine. I am away from the phone most of the time so I explained an email is best way to contact. That was several days ago and still no reply. Is this the normal service for this company?
