Vodacom ********** activity

I’m very disappointed ☹️ with Vodacom on Thursday Vodacom out of the blue do a sim swap on my number without my authorisation a day later then you allow some ********** person to port my number to MTN again without my authorisation and your IVR is really bad. Your customer care ppl don’t know how to assist when you encounter something like this. If I find that my number was use for any ********** activity during the time when this was taking place I’m holding Vodacom accountable for any ********** that may occur on my name with my number, honestly don’t Vodacom do security checks before action such requests?
