Tell the merchandiser to apologise!

Today, 29 May, I went to the Rensburg KWIKSPAR, at the till I saw Orbit Strawberry chewing gum priced at R9,99 I took 2packs and to my surprise they rang at R14,99 I then told the cashier that the shelf price is R9.99, the female elderly owner rudely told me to read all the details of the tag on the shelf, I told her that it read that the strawberry Orbits were R9.99 and said that at some shops, I would be sold the gum at the price that is on the shelf because its misleading the customers. The female owner angrily walked to the shelf read the tag herself and said its a mistake, and told the cashier to cancel them as she was not going to give them to me for the price of R9,99, I then said I was at least expecting an apology from her as the owner and manager of the shop for the misrepresentations and confusion of the shelf prices and that she would look into them, she then rudely told me to tell the merchandiser to apologise to me for not being able to read as its not her problem.<br> I was both shocked and disgusted that the elderly owner could have such a bad attitude and not care about customer service. I am disappointed and I will never again set foot in KWIKSPAR Rensburg.
