can't get what is advertised

Good day <br> <br> For the past 2 weeks I have been struggling to get any after service from Telkom, On website Teljomn shows IPHONE 5S 64GB for R259.00 but when I went to branch they told me they cant help and that its only a online order item. When I contacted customer care they told me that there is no option on site for this option, and that I should get it at my nearest Telkom store. So I went back again and they have no knowledge of this contract and I had to tell them to check on website, they then told me that there is no stock and they will let me know and keep me informed. This morning I went back for update because I did not received any feedback as yet. another guy assisted me and said that there is only one left in another store and if its already taken that he could not help then. So why still advertised if you cant keep clients happy. I don't want any help from this branch as this is not the first complain. But I am not going to drive and phone around just to be handed over to the next person. I want the gold iphone with the smart 50 packages. Please assist
