I have ordered some stuff the 21st of May, they supposed to be delivered in 3 days, we are now at the 9th of June and I haven't received anything. Every time I call they say that they will find out and then they disappear again...

Scam Company. Charged at point of sale (as per the norm) then followed constant account overdue letters (I've never had an account) numerous calls unanswered, when I did get through I was advised that the account would be rectified but no, just received further threatening letters for a debt that doesn't exist. I wonder if they send these letters in the hope that account will pay out without querying the false debt. Scam.

The product is well made and customer service pre-purchase was good. However once I had bought the product and I had a query absolutely no response to any of my three attempts to get advice.

I haven't managed to make an order, I really wanted too however my sale never progressed. I wanted to order around 15k's worth, to build a complete solution for m my property however the constant lack of responses to emails or phone calls, has left me in a state of mind that this company doesn't want my business. I rely on great customer service, and initially comms we're good, however nothing has materialised after 3 weeks of calling for a return call to proceed with my order, very disappointing. I expected more from a company that establishes itself as a market leader in it's solutions.

A beautifully made, high quality product. The technical assistance and detailed drawing produced by John Laughlin for the bespoke sized individual posts was absolutely excellent.
Delivery was exactly on time and the product was well protected for transportation

The ordering process was efficient and straightforward and the information which was provided to enable you to order the correct equipment was very good. A minor criticism if I may would be that having completed the order, it would be useful if an order number could be given which would be of use if there should be any queries.
