Vodacom basically misled me into taking a contract that would cost me more in the long run

Since Vodacom decided to close my previous complain with resolving my complain I am forced to lodge yet another one.....here goes nothing.

So based on the explanation given to me Vodacom misled me resulting me taking a contract that ends up costing more that what I budgeted for. The half baked explanation was that Vodacom does not offer Contract clients the Option to just buy any minutes for phone call purpose and only the for you promotional minutes of which to me they are useless. I remember very well asking the consulted before taking this top up contract if I'll be able to purchase minutes and he said yes and for almost a year now I have been able to purchase minutes until this current month when vodacom conveniently decided that top up contracts aren't allowed to purchase any form of minutes.

Now my stuck with a contract for the next 12 months plus that will cost me more on a monthly basis cause I can't afford to cancel it. And before some other consultant tells me about the T&C's , they themselves as consultants must know the T&Cs so that if I consult I am given the correct advise to make the right decision which did not happen in this case.
