Dear Mr. / Ms. ………[Name],
I am writing of a matter which I am confident will be of interest to you.
Last month (Month and date, to be exact), I placed an order with your firm for —–(nos.) ——— circuit boards. Having been told to expect delivery in the weekend time, I was upset that my order was not delivered as promised. Numerous telephone calls resulted in my being referred in succession to countless members of your staff who were unable to help me or provide me with an updated delivery date. [Mention detailed situation of bad service]
I would like you to know that I had foreseen the possibility of doing business with your firm in the future. Unfortunately, however, that will not occur if I am to expect this type of service. Surely, my unfortunate experience is not in alignment with your reputation, which I hear is of high caliber.
Warm Regards,
