Customer Name: Julian Jenkins.
I recently had work carried out by your group. I am writing to inform you of my satisfaction on the standard of the work and the approach of the engineers.
My wife and I were impressed by the engineers manner; we found them to be courteous and helpful. They contacted us over the phone on two occasions to arrange a time for them to call and on both occasions were true to their word and punctual.
I honestly believe them to be a credit to your company and even though I acknowledged their workmanship at the time, I would appreciate it, if you would let them know of my satisfaction of their part in the task carried out.
Thank you for a job well done!
