Shocking adverts with no stock available

Makro advertised a 200GB prepaid smartdata package on 7 November 2015 in their Cell C pamphlet. I went to Makro Milnerton on the 08/11/15 and wanted to purchase it but they had no stock. As the special was on till the end of January 2016 I proceded to call Makro weekly to ascertain when they receive stock. On 03 January I called for the seventh time to ask if they received stock.I also called their other Cape Town branches with the same answer. They do not have any of the prepaid data packages in stock was the reply and they don't know when they will get stock was the reply. I find this totally unacceptable from Makro, why advertise something when you do not even have the products. Not even a raincheck was offered or the assurance that they will keep stock when they do indeed receive it. Makro you are wilfully manipulating the system and not following the rules laid out in the consumer protection act. You are indeed misleading your customers and treating them with disrespect. Shame on you.
