Ordered Villeroy & Boch tap and waste for a deck mounted basin, as shown on the HeatandPlumb website photo shown below. The narrative did not say that the supplied waste would not be compatible and the order process did not give any opportunity to select a different, compatible, waste. HeatandPlumb say their photos are "purely illustrative" which means that the fault is mine for believing that I would get what they advertise. They will accept a return of the complete order, presumably at my expense, but I paid £84 to have the tap fitted and it will cost the same to get it removed, so that's not realistic. A reasonable supplier would simply exchange the wrong waste for an appropriate one and change their advert to avoid other people falling for the same error but they flatly refuse to take either action.
