False Advertising by Sterns N1 City to bait customers into buying.

I am a customer who shops at N1 City frequently and pop in now and then to see if there is a nice bargain to be picked up in the Sterns. Last week Thursday I walked past the window of the branch and to my amazement saw the bargain of the year. A ring was advertised for R1299. I waited for the lady inside to finish with customers before I asked her if the price was correct. She then very shyly said no, it was not and it was a mistake made earlier by one of the other staff. She then removed it and apologized. I, understanding that such things do happen said all was good and went on my way. On Saturday I walked past again and was shocked to see that the same price was on the same ring, which led me to believe that it definitely should be the price. I stepped inside and spoke to a lady by the name of Nurroenessa and explained to her my experience and my concern and told her that certainly I should be afforded the price on the item as you can't repeat such mistakes in a professional company like yours. She called her regional manager about it and the regional manager just said that she should tell me that I can't have it at the price I saw twice in a row. She then gave me the details of customer service/complaints, hence here I am. Poorer service have I never seen in a retail business, and I have been in retail for almost thirty years. What is your policy on such issues, or does Sterns not comply with CPA requirements and not care about their clients? Bait marketing is an old trick that should not be taken lightly, as we the customers spend our valuable time arguing about our right to buy what we see because it is our right as customers to be treated with honesty and integrity.
