"Unacceptable - Refuse to communicate"

In my 10 years as a buying manager in the fashion industry, I have never experienced communication this bad! Our company have made a small wholesale order for about 3.000 GBP, and Underated apparently refuse to reply e-mails or to communicate after the payment has been successfully transferred (13/2-14). In their terms they informed that the shipment will be done within 14-21 days after successfully payment. Despite we still haven't received any information, products or what so ever. Everything can be documented and it is our duty to tell everyone not to do business with this company!
