My experience relates to a purchase made at the Dulwich store which has since closed but as I had extensive dealings with the Head Office I feel it is relevant to post it here.
This shop had some beautiful curtains for sale at great prices but their customer service is shockingly bad. I purchased a pair of curtains for my very wide 5m patio doors. I gave all the measurements to the assistant and she pointed out just 2 or 3 that I could choose from due to the unusual size. Fortunately one pair I loved and bought them there and then. I had them taken up professionally (at a fraction of the price quoted by the Curtain Exchange for this service) and excitedly started to hang them at the patio doors. Only at this stage did I discover that the dappy assistant had sold me curtains that were only 3.5m wide!
I could fill pages detailing the tedious correspondence back and forth with the branch and head office trying to resolve this problem but suffice to say that they were disinterested, unco-operative, lacking in the basic courtsey of returing calls and wholly unpleasant to deal with.
After weeks of chasing, I finally managed to secure only a credit note to the value of the original curtains, by which point the Dulish store had closed and I had to trek to Fulham to find replacements.
I can honestly say that this company provided possibly the worst customer service I have ever encountered and dealing with them was a stressful and unpleasant experience throughout.
They're not as superior as they seem to think they are.
