Query: 28 Days DVD

I have never received the product. I ordered it March 3, was informed it had been shipped, guaranteed delivery within 15 working days, and my credit card was charged. I have sent emails to both Amazon.com and DVD Legacy, but have not received any information regarding my movies. I ordered 6 copies of the movie "28 Days' for use in a college course I am teaching.
