All I want is a simple SIM swap

I got a new phone with a new SIM card for my wife, so I needed two SIM swaps - one from my wife's current phone to the new phone and one from my daughter's phone to my wife's old phone. After calling customer care three times, the SIM swap from my wife's old phone to the new one was done in a few minutes. Clearly the first two operators were in no mood to help or had no clue as to how to do this. They were full of excuses, while the third operator helped quickly and efficiently, without complaint. Another five calls to customer care later, I have yet to get through to a helpful operator again. They are all full of excuses and stories - not one of them the same. One says I need to buy a new SIM, another one says I have to RICA this SIM (stupid, because I already did), another one says the network is offline so call back tomorrow... what absolutely terrible service ! If the other network operators didn't suck so much more, I would have moved... but we are stuck with Vodacom and their pathetic customer care operators. All I want is a simple SIM swap !
