False advertising

Telkom had a special since 20 Jan - 20 Feb for a mifi router, laptop, data bundle n free microsoft package. To date they hvnt had stock, I hv been to cresta a couple of times n was told they don't have mifi routers n wanted to sell me a different packagem on the 19 Feb went to greenstone and was told the special ends tomoro and they hvnt had stock in a while. They were advertising something which was never in stock.
