Not honoring prices

Disgusted with Makro Montugue Gardens service today! My husband went to the liquor department and wanted to purchace the gift set for the price as per the shelf. As one can see in the photo the tag shows R149. When he came at the till it rang up for R749, and he requested a manager. The floor manager Mavis Ntshuntshe came and he showed her the photo whereby she agreed that the price shows R149. The cashier then continued to advise her that it is R749. They then went on and blamed a faulty price tag and was only willing to give me R149 off the price. I was not happy with this as this was misleading the customer and even the manager herself agreed when she first saw the photo. Cheragh Constable then came and also offered the same excuse. This error is not your customers fault and as per the Consumer Protection Act you need to honour this and take it as a learning to fix your faulty equiptment. I want the product as advertised.
