Dear Madam
I made an order for some profuct samples from yourselves over a month ago. I am now in position to make sales based on these products and although I have prospective customers lined up, I sind I have nothing to show them. I have enclosed a copy of my order which clearly showed that I paid for express delivery.
I would appreciate a prompt phone call on [phone] on receipt of this letter to advise me on that progress there has been on order. I look forward to your quick response
