Cheating with prices

On sunday 14 July I went to Rochester mall@Reds in Centurion. I was attracted by a plasma stand priced at R2 599. When i was paying for it, I was informed the plasma stand was actually R3 695 and therefor they couldn't sell it to me for the price placed on the item. I requested to speak to the store manager. I was then told he was not available. The sales person,Keleabetswe then contacted him and he promised to resolve the issue by Monday 15 July. On 15 July he called to say the price was incorrect on the item, and that I can only buy it at system price.I told him I saw the price at R2 599, and that's what I am willing to pay.He said its beyond his authorisation level, therefor he cannot assist me. On the same day I contacted Rochester head office and was promised to be contacted within 8 hours. I called again yesterday and today, as no one has contacted me. It seems like no one is really interested in assisting me on this matter.
