Bought a 6x4 green house. One of the most complicated constructions, with one main bar missing and damaged roof panel. I have sent photos of the damaged panel 3 times, and been told they were not received. Now have to wait some 72 hours or more before I get a replacement. So at the moment a greenhouse with a gaping hole in the roof. This is the first time I have bought anything from Robert Dyas, and will probably be the last. I would warn anyone intending on purchasing a Poloma 6x4 green house that it is a complete build and and not in sections. This is not made clear when you purchase to my knowledge. Not happy
