I understand the OP's frustration but I think this is fairly common. These tiny companies with high demand for their products (Decware, AVA, Zu, etc) don't have the staff to continually update customers on outstanding orders while fielding questions and orders from new customers (and maintaining quality control!). Decware was smart to create their order status spreadsheet, but a lot of companies don't want the hassle of moderating their own forum.
I find that a simple followup email usually generates a good response from the manufacturer.
