My Continuous battle with Vodacom

I ordered 2 Iphone 6 Plus 128G Gold in color on the 16th of July 2015. I was told that the devices would be delivered by Ram on the 17th of July however I asked if they could be delivered to me on the 20th as I was out of the Province. A week later and numerous calls to ***4 have proven fruitless. I was told that there is no stock of the 128G so opted for the 64G. Nobody can tell me when my order will arrive or the status of the order. I then took the liberty of calling the warehouse and a gentleman by the name of Willem confirmed with me that there are 32 units of the 128G in stock at the warehouse. I then called Sales back and the people I have been dealing with refuse to take my calls including the manager. I am an existing Vodacom customer and was talking 2 extra lines but I am wondering whether I should switch to a more reliable network operator. Really expected a little better service from a company I rave about to other people.
