First and foremost, the structural stability, and strength of the four "heavy duty" shelving units I bought is nothing short of terrible, it's extremely lightweight and somewhat unstable, and unsuitable for average use in a garage or similar. My problem started when dhl left the parcel in the middle of my front garden in full view from the road, in 4 boxes that looked like they'd been abducted and mauled by a pack of hyenas, luckily only a few of the feet were missing. When I finished doing the unpacking that dhl started, I built up the units, well, tried, as one crossbar was completely bent at one end, and one tab on a cross member is snapped so I can not add the supporting brace and a couple of the shelves were to big to fit in the shelf space so bow up. I contacted customer service in regards to the disgusting delivery standards, the state of the units themselves and the false advertisement and use if the word "heavy duty", when the items are in fact, far from being legitimately described as such. I received a response, majority of which completely dismissed my complaint, but concentrated on the words used to describe the work ethic of the delivery person, apparently my suggestion of euthanasia was "offensive language", I was offended by the work carried out by dhl and the ignorant response from Leigh Alder 'customer service manager' who apparently can't manage to put together a half decent response to a serious and legitimate complaint. All conversations have been saved, logged and will be heading to the relevant department atvtrading standards, along with cctv of the delivery guy. A complete lack of options in regards of a resolution to the list of issues goes a long way in explaining the reasons why I'd be well entitled to honestly advise against buying from this company. Steer clear.
