Lack of transparency and accountability

On Frebruay this year my instalment got increased from R2058 from R1 978 and when i went to Acornhoek Mall branch i was told its fixed until today they told me it’s VAT increase. I called client care and the first consultant told me the same thing and transferred me to another department where i was told there is no VAT increase he is transferring me to billing department for clear explanation and when he did was told MTN has it own VAT they increased prices because on their subscription because their VAT increased.
