Dear Hennery smith,
I would like to draw your attention to your excellent receptionist, Janet Hunt. Yesterday Ms. Hunt took it upon herself to try and resolve our issue. This meant taking a lot of time and effort on her part, and did not stop until she found out what had happened with our accounting issue. It was an example of a rare case of professionalism in our industry. I believe Ms. Hunt to be an integral part of your company, and it is because of her that I will be passing on more work to yourself in the near future.
Sincerely,
Paul smith
