Online upgrade - EPIC fail

Vodacom - Can someone who handles online upgrade requests actually do their job and please call me back within the next 24 hours ! I have submitted my New deal requests over a week ago - No one has called me back to finalise the deals . The number ********** 4 just rings and has the automated machine talking to you . The whole process is frustrating and I honestly don't see why it should be IF people just do their actual jobs! Clearly customer service delivery is not a high priority. I have had my contract with vodacom for over a decade now - maybe its time to move to another service provider and save myself the frustration.
