Thank you for your prompt assistance in providing a couple of weatherbars and their fixings. I think I should owe you something for those - if so please invoice me or give me a call and I'll send a cheque.
Whilst writing I would like to add that overall we were very impressed by your prompt and efficient service. From the planning and ground clearance to the base construction and product installation, we are very pleased with the garage and will not hesitate to recommend you whenever the oppurtunity occurs.
Kind regards and best wishes
