Dear Mr. Miles,

We are very disappointed with the shipment of commercial quality baking pans we ordered from your company on May 10.

Our order no. is 806321. The pans we received were not only full of rust but were also scratched and completely unsellable. Attached please find photos of the items.

As the products you sold us are obviously of poor quality, we request an express shipping of a replacement order with the quality level agreed upon in our sales contract. Alternatively, you could provide a full refund.

We look forward to hearing from you soon.

Sincerely,

Wilson Tan

这是一封写给销售商的投诉信。信中说明了订购日期和订单号，并详细说明了产品存在的质量问题，还附有照片为证。最后，提出了两种解决方案。问题描述较客观，语气也较礼貌。
