Robbing customers instead of caring for them - what is the whole purpose of "Customer Care" then???

I was sold an upgrade with false and misleading information. I insited on speaking to the relevant Department to refer to the voice recording of the sale and for matters to be rectified immediately, but only got cut off by Vodacom. I am furious, as we already pay such high fees for services and data, just to be ****** even further by conniving, untruthful sales people!?
