Upgrade - No stock available

Hi<br> I tried now for more than a month to upgrade my Telkom current contract (that had expired) to a better one and the one I choose is the one where you advertise on all the TV Screens and booklets in the stores in Centurion where you can get a explorer with the deal. With no luck I have tried all the Centurion stores. Every time I get to a store, if it is Mall @ Reds or Centurion they keep on saying they just went out of stock but I have had this excuse now for more than a month. After I have given my number to everybody and send a couple of emails I get the same response. (No stock and we don't know when this will be in stock again.)<br> Please don't advertise something that you can not deliver.
