This experience was a just so amazing…

This experience was a just so amazing from start to finish. Mackenzie showed me around when I visited to view the Basebox. She was really friendly and so well informed. She had all the info I needed and a couple of questions she went and double checked. There was no hard sell - just a genuine enthusiasm for the product. I was then contacted by Nicole who oversaw the planning of the times etc. Nicole was also so very helpful. She was always quick to respond and reassuring. She kept everything on track and was a delight to talk to.....she put up with some silly questions from me! lol Everything thing was done on the day it was planned for. All the men who came were a pleasure to have around. Polite, hardworking and very dedicated to doing a good job. They were also enthusiastic about working for Green Retreats which is always a good sign. They were a credit to the company and deserve recognition for this as they are the frontline of the company. A special shout out to Adam and the gang who did the installation. There were a couple of obstacles- e.g. traffic due to an accident on the route, one man down - but they stayed late until the job was done - such commitment - they worked soooo hard. They even came back another day to double check in daylight that it was to the high standard they wanted to deliver. The foundations men and the electricians and WiFi guy had the same dedication. Sorry - so many names I couldn’t remember them all. On top of that I am over the moon with my Basebox! It is even better than I imagined it would be - an excellent product. The interest free credit is such a blessing as well. It meant i didn’t have to spend all of my savings or remortgage.
