Clearwater Branch Has no need for paying customers

I phoned them early this morning regarding a laptop they were advertising. I confirmed the price and the availability of stock. I took time from work and went to Clearwater mall branch. Upon my arrival I was told the sale only starts tomorrow. After the sales person ran around confirming they have stock just waiting for the store to open he came back and said I cant get it for the price of R5999 which was the special and was told to pay R 6999. Or I need to come back after 16h00. The salesperson took me to the main counter where he started to attend to another customer and asked a lady, presumably the manager, if we can sell the laptop at the special price. She told him to ask the manager. He said to her that she is the manager. She turned away from and start to speak in a language I don't understand. I ask if they want to do the sale or not. I got no answer. In today's shrinking market and economy I would have thought that bad customer service would something that would not be possible. Yet it seems that Clearwarter branch view the fact that a willing customer can walk out of the branch not making a sale as OK. This experience was bad and non existing and frankly I found it to be a bit ******.
