Price is not the same as the store catalogue

The online catalogue has the Sony MX3 headphones at R4499 sale running between 25 August to 1 September both online and at selected stores but when I went to Centurion Mall to buy the same product I was told actually this costs R6999 and is not on special. They were confused when I showed them the catalogue they are supposed to be aware off. Wasted my time, no longer e-commerce is killing them they're a nuisance to deal with.
