Pathetic customer service

Hi, I've been to Game (Gateway) three weeks ago. I was hoping to purchase a iLife tablet which comes with a free smart watch. It was advertised in the Game catalog for R999. When I inquired about the deal as they were out of stock a lady at the front desk assured me that as soon as they received stock which was arriving during the cause of the week I would be informed. She took down my details and I left with a positive attitude knowing they will keep to their word. A week later the new Game catalog was out which had the same deal and to my utter disappointment I was not given any courtesy call. I been calling them on many occasions and have been met with frivolous excuses and not much help. How can a special be advertised two weeks consecutively and the store have no stock? I am very unimpressed with their service and lack of customer service.
