The builder/installer was very good in terms of quality of work, help and assistance during the work and punctuality/cleanliness. Customer service from the main contact at Mark Two, Alex Whitton, was very good. There were a number of issues with Mark Two relating to delivery of items re accuracy and timeliness. Their service manager, Jim Bryson, was on site on the second day and promised to visit every week. He even took pictures for before and after comparison. However, he was no where to be seen after that, and was not at all responsive when issues were raised. Probably the worst service manager I have ever had to deal with. The worst of my comments relate to Debenhams. If you think you are dealing with Debenhams, then be warned. They take the money and then refuse to get involved during the process, even after multiple requests. I went with Debenhams because of my misplaced trust in their brand name and reputation. Never again.
