Vodacom sim swap *****

I have had multiple attempts (4 attempts) to do a sim swap on my business cell number in the past 5 days. Every time this happens I call Vodacom as I have not requested a sim swap and I get told various stories. The most plausible story which I was told last night by your call center when this happened again is that it’s ***** being perpetrated within Vodacom. I cannot keep having these requests and wasting up to 1 hour on the phone each time to cancel the sim swap. I want to cancel my contract because Vodacom either cannot do anything about ***** or have employees complicit in it. I’ll then transfer my line to another network.
