REFUSAL OF REFUND FOR SHELF PRICING ERROR

I recently visited the Whalecoast Mall branch and purchased 2 quite pricey deodorants for my son. These were priced at R75.99 each. When I got home and checked the slip the one deo was charged as a body wash for R92.99. A difference of R17. When I went back to get my difference in cash back i was told that it can not be done. I explained that I did not buy a body was so why must i be happy to be charged for it. The manager did not even come to me just sent supervisors to assist. I am shocked at the service and answers I received. It is also not the first time that this has happened. Often there are special marked on the shelf and when you get to the cashier it is still at the original price ...nothing special! I am very disappointed in the service the answer and service that I got. What if the difference was R100 would the answer still just be ...sorry it can not be done like that. I suppose somebody has to pay for the clubcard points. I still have the slip in case management realises the unfairness of this transaction.
