Vodacom ridiculous hidden fees

I have an open query with vodacom for more than a month now where I explained to them that they should listen to the call recording between myself and consultant who assisted me with my contract upgrade as the amounts he told me are not the same as the ones vodacom debited. All of a sudden there were lot of hidden fees that were never explained to me. I want this resolved before the next debit order goes off. They cannot just ignore me.
