Not keeping their promise

I app**** for the R299 iphone 5s 64GB deal. I confirmed thrice if not more with the agent who did my application telephonically that I am applying for the 64GB. He assured me I will be getting the 64GB. It is now almost 2 weeks since i app****. The debit went off my bank account. I was supposed to get a reference number for my order. Nothing. Made numerous calls to the call centre (was on hold for so long). 1st i was told the person who did my application is on leave and will inform him to follow up on my order when he is back. I requested from this agent who advised me of this to do the follow up instead and call me back. To date no call. I went to a Telkom Mobile store with the hope they would assist but online and store applications are not the same and the sales department is closed on a Sunday. Fine. Monday comes. I call again. Khanyesile tells me no order created, I insisted it to be done. Put on hold, comes back and say no 64GB available, not even 32GB. Only 16GB. Spoke to manager, Cynthia, repeated the same as Khanyesile. Their reasoning was contradicting. Was put on hold, got disconnected and no call back. Their incompetence ****** me of a 64GB which was promised to me :(
