Can’t do a sim swap

Vodacom has not reached out to me, I tried to do a sim swap telephonically which was not a success and was advised by needed to buy a contract sim even though I am no longer on contract, I then went to a Vodacom shop in Greenstone mall where I was advised the sim is R160 and service for sim swap costs R65 however there’s an issue with their system and therefore they will not be able to process my request. I then called Vodacom again and told them about what happened at the shop and expressed how I’m also not willing to pay over R200 for a new sim when I am not even on contract anymore and was advised that it’s possible to do the sim swap and I needed to buy another sim but not register it and it will take a few days for the sim swap to be processed. This was on Sunday, I call on Wednesday to get an update on this and I’m told I have to buy a contract sim which I’m not willing to cause I was told of this other process, also it makes no financial sense when a prepaid sim is like R1 and I have to pay over R200 for sim when I’m not even on contract anymore. The number in question is ***.
