Vodacom - Failing to deliver on advertised product

I upgraded my Vodacom Red contract this month. I requested they include the Iphone every year deal on my new contract. Everything was in order when I signed the new contract. As per terms : http://www.vodacom.co.za/vodacom/terms/new-every-year-terms-and-conditions

Since then I got feedback from the Vanderbijlpark branch where I signed on, that this service is no longer available. I've tried to call Vodacom help center but they fail to give me any valid feedback.

My company has been a loyal customer of Vodacom for many years. This is really unacceptable!
