I went to B&Q at Cortonwood Barnsley this evening. I asked for help and told the lady Sarah I wanted WHITE paint for interior walls that I could wipe clean. She was more than helpful and advised me on the Dulux Endurance range, also telling me that they had an offer on 2.5L where they were 2 for £32. This seemed just what I wanted so purchased 4 tins along with other items. After paying I thought it seemed to cost more than I thought it should. So I went back into the store to customer service to be informed that it was because "it was WHITE paint" and that White is apparently "not" a colour but a shade, and that technically "black" although B&Q class this as a colour is actually a shade. Frankly I don't care about the black paint, I didn't want black paint I wanted white paint. And all I was advised was Sarah got it wrong, and I even pointed out their POS stated "ALL DULUX ONCE, KITCHEN, BATHROOM & ENDURANCE COLOURED EMULSION, 2.5L 2 FOR £32, and that nowhere does it say excluding "white paint". Then I was offered to bring it back for a refund. By this point my husband had already put all the shopping in the car along with our 4 year old daughter, so I decided to call Head Office and speak to a reasonable person. Alas this was also not to be, the person Alistair spoke to his Manager to also inform me that 'White" is not a colour and they could not log this as a complaint. So despite asking for help, specifically asking for white paint, being advised based on my needs, the Brilliant White Dulux Endurance 2.5L which was on offer was what I needed by Sarah, B&Q at Cortonwood refuse to rectify their mistake so instead of paying the expected £64 I ended up paying £99.76, a total of £35.76 more than I was advised. Tomorrow I will be returning everything I purchased today a total of £156.01 and will not be purchasing anything from this store again. I am a Manager in retail and had one of my staff made this mistake I would have honoured the price but B&Q's answer is to lug all the paint back into store to refund then spend my time all over again looking for a suitable alternative. Terrible customer service.
