********** sim swap approved by Vodacom call centr

1. On 05.06.2015 I received an sms from vodacom that a sim swap had been authorised on my phone. This was **********, so I called vodacom immediately, reported the *****, got the sim blocked and blocked all my bank accounts. <br> 2. On 06.06.2015, I had to do my own sim swap to get back my line. At this time, I logged a complaint with vodacom and requested an investigation. I requested the phone record of the ********** authorisation. I want to know how the caller bypassed the security questions and received authorisation from vodacom. I was also shocked that there was no record on the system that this ********** sim swap had taken place.<br> 3. On 07.06.2015, I again called vodacom about the investigation. There has been no response. To me this is very slack
