Vodacom is working with ********

How do you allow a Sim swap to go through without my permission? As a result, ********** were able to make payments to the value of +R8000 using the cell phone banking channel. When I first called I was then informed that Vodacom cant help me to block my number cause now my number belongs to Cell C and a Sim swap authentication was done as per call centre procedure. $ days later my number now works under the Vodacom network ???? Am I missing something? What is that procedure? What security questions were asked? Can Vodacom provide a call recording for that? Is it so easy for Vodacom to process Sim swaps without the necessary verification checks. and then take no accountability for the mess they have created.
