Ordered a "sit -tight" toilet seat, which required glue (provided). When I came to fit the seat discovered the tube of glue was rock solid. When I contacted QS they asked me to provide a photograph of the "damaged part" (doh!). I did so and after a couple of days was advised (by them!!) to remind them if they hadn't contacted me within a certain number of days. I had to do so and eventually they got back to me advising that a replacement had been sent. As it hadn't arrived after more than a week I contacted the manufacturer ( Croydex) in desperation. They were fantastic and provided a replacement overnight, together with a spare pack of parts to enable me to complete the job. They seem to have quality goods but are useless at customer satisfaction.
