Sanitaryware Centre False pricing

Bad Experience with online shopping at Sanitaryware Centre, due to waht thet called "an error in pricing" pricing a kitchen sink. I paid for a double basin sink based on the picture provided and order was confirmed as such. Later I got an email that was asking me what I intended to buy as they have identified an error in pricing and asking if I wanted a single basin sink? I clearly bought a double basin and when I confirmed as such for them to honor the order, they refused but were quick to offer refund. Talk about convenient "mistake" to lure unsuspecting shoppers. Take extra care when shopping at Sanitaryware Centre to avoid disappointment and waste of time. Will report same to relevant ombudsman.
