Vodacom upgrade with Elite Mobile

What a TERRIBLY disappointing experience. The lady who initially called me to inform me that my contract was due for upgrade & who assisted me with upgrade options was top notch. After that I was put through to the supervisor to confirm the contract upgrade. Since then I received 2 separate calls wanting to confirm my upgrade - really/?????? Upgrade call happened on 21 Feb & when I called now to follow up `I was informed that the iPhone contract I wanted is not available. SERIOUSLY!!!!!!!!!!!!!! Totally unacceptable & NOBODY got back to let me know this????????? This is sooooooooooo NOT ACCEPTABLE
