I am not sure why you are not receiving the magazine, I have not had that issue. As for the books, sent them back. Most companies that send this type of mailings out have a return label in with thim. I also understand that under NC law states that a person is not required to pay items they did not order.
I have contacted the NAHC years back to correct an issue but do not remember the path I took. I am pretty sure it was an emai address listed on the website.
Good luck getting this settled, the magazine does made for interesting reading.
