Gentlemen,
Your letter of September 10 brought us the invoice(发贷清单)of your last shipment; and with the exception of the item forming the subject of this letter, we have found all the goods quite satisfactory.
With regard to the 30 pcs. No. 100 Silk Crepe, however, we much regret to find ourselves under the necessity of rejecting them, as they are wrong in both quality and width. The quality is far below the pattern on which we placed the order with you; the width is narrower by 2 inches than that ordered. These errors on your part will cause us to disappoint our important customers, to whom the goods must be delivered, and we are now placed in a very awkward position.
We hope you will put the matter right at once, letting us know by cable what you are going to help us out. Carelessness of this kind makes us incline to give our orders to your competitors.
Yours faithfully
