Can somebody teach Vodacom customer care, and will they listen

Once again I have been subject to the general poor customer service from Vodacom. I tried phoning to migrate my plan, got passed round to 4 different people, having to provide the same information every time, having to do the same verification questions every single time, only to be cutoff after 20 minutes. The excuse remains that I'm still on the "Old" system, whatever that means.
