Wish I read this site and the Money Saving Expert site specifically showing all the issues everyone has had. My customer service issues have almost been a mirror image. Luckily my defects are due to poor workmanship, mitre joints with gaping gaps in the windows, white wood filler in the doors front and inside, faces of the planks peeling off, faces of the planks where the planer obviously dug in. it took a long time to commit to buying a product sue to the expense and work required and now i wish i bought someone elses. Do not touch their insulation kits just go to the builders merchants and make your own as that what they do but with a 4x multipiler. The sales quoted delivery to me in 3 weeks... I acknowledge the dishonest comments in these reviews as that's how i feel, misled for a sale. the next week i had a text saying it was out of stock and would be 40 days for delivery.... 8 weeks. After numerous emails, not one replied too i had a delivery date of 7.5wks. I complained it was reluctantly moved to 6 weeks on the dot, conveniently inline with their T&Cs of 30 days. still no written correspondence from them. Suddenly leave them a review on trustpilot and you cant get them off the email, but they wont respond to you points or queries or acknowledge they were at fault and have caused significant distress. As I've seen here, use at your peril. For the moment I have a useable cabin, we'll have to wait and see on its longevity. I dont think i'll ever be completely satisfied with it due to the stress and issues caused in the build by DH. I would say the delivery guys were very nice, the only customer face of DH.
