Vodacom allows ***** even after I warn them

I have been struggling with this for over a month. I have spoken to call center agents, team leaders and forensic investigators, all of whom have not solved my problems or given final feedback. I have logged service requests to have my numbers flagged to prevent people from doing ********** sim swaps on my numbers. It was confirmed to me that the flags have been made. Since then they have still managed to swap three of my sim cards telephonically and they have charged thousands of Rands of content to these numbers. I truly feel that no one at Vodacom cares. I have spent hours phoning the call center trying to resolve this. I have been a loyal customer for years now. I have done my best to prevent this by notifying them in advance. I was guaranteed that measures have been put in place, but still it is happening. When I ask them how this is possible, they can't give me answers. I do not feel safe with this company. This is out of pure desperation that I am on Hello Peter. I want to cancel my Vodacom numbers. I expect someone from Vodacom to call me urgently. I have all the names of people I have dealt with. I want urgent resolution! This is the third *****ulant sim swap in a month!
