We have just agreed a contract for your company to supply and install replacement double glazing, bargeboards, soffits fascias etc. to our property.
We wish you to take note of how impressed we have been with your sales representative, not only for his professionalism and technical expertise but also for his courtesy, patience and good humour. He has been tireless in taking the time to explain everything clearly and we are most grateful in view of the fact that this work is such a large commitment on our part. We look forward to the installation which we are sure will meet your usual high standards.
We would also like to take this opportunity to ask you to pass on our thanks to your sales representative and to wish him and your company continued success in the future.
