*****ed Vodacom

Vodacom please help me understand how taking a month to month contract that costs amount X , changing it to a 24 month contract for the same amount X and charging amount XX for doing that amounts to an upgrade. Your *****ed sales agent said she was downgrading the existing contracts so that we would pay less, we get a bill that's more than what we have been paying and, when we call the call centre, we are told about this so-called nonsensical 'upgrade' that was never explained to us. Please reverse the 'upgrades' that you did on the 2 numbers and credit the vodacom account with the extra amount you charged.
