Sim Swop without Approval

<p>I have had numerous issues with my vodacom account as of late, for the past 2 months I have had people trying to process a sim swop on my cell number without my approval and they were eventually succeeding. This whole dillema has me endeaour hours of my phone being blocked, then having to process 2 sim swops done myself as initally i did a sim swop and somehow they are still managing to hack my cell account. Daily i have to contact Vodacom as my number is not working optimally. Vodacon has assured me they have flagged my account for fradulent sim swops yet this is not seeming to help. </p> <p> </p> <p>How is it possible for a non-account holder to get a sim swop processed and with all the security questions? This whole issue has even lead to my bank accounts being hacked at two different banks. </p>
