false advertising and very rude Store Manager and Head Office assistance

I was at Toys r us in Boksburg yesterday. My son chose 2 items off the shelf which were Monster Jam marked at R149.90. My son had R300 to spend therefore after seeing the price I informed him that he can choose 2 of the items due to the price. When we got to the till the cashier notified me that the item was R349 I then informed her that that price was incorrect. She then told me to walk with her to the shelf and saw for herself that the price was as i had stated.she then called the store Manager whereby they had swoped the pricing around. I then informed her that I was not othe only client and that there was another client in the store that had also taken 2 of the same items due to the price .armed on the dhelf. We both then informed the Manager that this was false advertising and we want the items at the advertised price, she told us no we can go to .edua as she cannot give us the items at this price falsely advertised nor will she be at yo give us any discounts on the selected items. . I ge this is very wrong and as a customer we have the rite to take the items at that falsely advertised items as we don't work in the store. We yhen proceeded to contact Head Office we managed to speak to a senior consultant by the name of Bianca Johnson she refused to assist us and told us that she has the rite to refuse us according to the consumer protection act. The other client asked her if they or myself are expected to read the barcide and therefore he will come and protest to i dorm the clients that they must read all bar codes as they are falsely advertising in the store she was very rude and said thT she will then have him removed from the store if he had to do so. In the end my son bought a gu worth R300 and the other clients bought worgh R1000 + however I feel that this is highly unprofessional and unpleasant the way this was handled and I expect a call back and this issue to be resolved. I await your response.
