Vodacom call Centre

My experience with the vodacom call Centre was a terrible one. A sales lady contacted me regarding my contract, **** to me regarding the amounts I'm currently paying and advised on lowering that premium and insisted on activating another plan which would work out cheaper, when looking at my statement, I saw the amounts she gave me were indeed overpriced and incorrect. I was **** to on a recorded line. I then phoned in to cancel the migration she insisted on doing, and I haven't gotten assistance for over a month now. I'm told there's no email address to query this, I keep getting told it will be canceled but as expected, nothing is being done. I am however still getting calls from vodacom trying to upsell their products and disregarding the cancelation. The call Centre agents do their own thing and abuse the 'your voice is your signature' law. I do not recommend upgrading your contract or getting assistance via the call Centre, it is best to go into the store and see what exactly their system reflects before making an informed decision. The call Centre is truly pathetic and a huge disappointment.
