Did a quick search and NWTM got an F from the
BBB. Most of the complaints were for delays or nondelivery of large silver bullion purchases not coins. There are probably only a few manufacturers in the low volume collector coin industry to choose from. NWTM did do right by Kialara according to the
Kialara blog. Bugging customer service every day, or asking for the dies might make the problem worse. You want the company to believe you will be a repeat customer.
