Vodacom false marketing

I am trying to upgrade my contract – and as they market it, I am trying to do it online – It gives me a package that I qualify for, then when I choose it, it throws me out and says I do not qualify.

I spend hours online with consultants that are not able to assist me – They can give me packages with not enough data or not enough minutes – or a plan way too expensive that I do not need –

I am allowed to cancel my contract and take out a new one that will be custom to what I need – but that I Crazy – I took a screenshot of the deal they tell me I Qualify for and then I cannot do the final submission. I have been holding on for 27 min on the phone to speak to a manager then they cut me off.
