I am writing to express my thanks to you, and your staff for our successful network upgrade. Having gone through a similar exercise in the past, I was anticipating some “frustration”, however each and every step of this process was handled in a professional, efficient and courteous manner by all your staff. It would be inappropriate for me to recognize one or two members of your staff for their efforts, so I am sending each person involved a copy of this letter, with my sincerest thanks for the effort they put forth.
We now look forward to a long and mutually beneficial relationship with your company, and if you wish please feel free to offer our name as a reference to future customers. Once again, our thanks.
