"I am writing to thank you for superior service and professionalism. In recent years, I have had a great deal of contracting work done on my home, but to date, your company is by far the most impressive in its execution of service. Your team arrived when you said it would. The men carried out the work in a timely and effective manner, and my wife told me that you came by at a later time to inspect the work and repair a small area that wasn't exactly to your specifications.
Yesterday, we received your invoice, and I was delighted to see the warranty and guarantee among the contents of the envelope. In this day when so many individuals complain that customer service isn't what it used to be, I am delighted to say that your customer service is superior, and I wish to thank you for that.
I noticed in your yellow pages ad that you are registered with the Better Business Bureau. Please feel free to forward this letter to them, of if you will provide me with the appropriate contact information, I will be more than happy to do it myself. Also, if you ever need a customer reference, feel free to have potential clients contact me."
