Bad Customer Service

Hi ladies just need some advice. I have been to @ home in Ballito junction today. There were mark downs. I took 4 things which I thought was ridiculously cheap. When I got to the till point I was told sorry it's the incorrect price. I asked to speak to the manager. He told me sorry its a human error and I cannot get it for the price it's marked down to. As far as I know is that the customer always gets the marked price. I put up a fuss and he called his area manager. The area manager spoke to me and asked me how many items I am taking. I told him 4. He said he will call me back. After a while he called to say he spoke to operations and unfortunately I cannot get it for the price it was marked. I also told him that according to customer protection act, the customer always gets the price marked on the item. He refused.i spent abt and hour in the store and left with nothing. So disappointed.
