Musica cannot keep up to their advertised price.

Friday evening. My wife and I go to Musica Eastgate Mall to purchase a wireless bluetooth headphones for our kids. We see the Seinheiser headphones priced at R399.95 so we decide to take 2. When we get to the till to pay. The store manager Peggy quickly come to the tills and says the item are not for sale and the reason for this they marked the items wrong on pricing. Now as a customer it was displayed at a certain price so it must be sold at the price. The manager duty is to make sure that the items that are advertised are priced correctly. She refuses to give us the items at that price. So i make her sign a letter to say that she refuses to give us the headphobes at that price. I want those items at that price advertised. I will not accept the original price as it was not our fault. I have taken pictures wer all the boxes reflects the price of R399.95.
