Tricking customers to buy the wrong bundles

Bought a voice bundle for R5 for an hour on the Vodacom app. But before I bought I search for it on Vodacom's website and for I saw and understood that I can call any network. But this wasn't the case. So once again Vodacom take changes with customers again and doesn't show for what the voice bundle would give you, hiding the truth. Now the R5 I had is gone. The app doesn't give clear info what the voice bundle will give you access to. How must the customer know Vodacom and then your customercare people or services tends to be very arrogant!! Once again brilliant work Vodacom
