Vodacom allowing ******* SIM Swop

Vodacom allowed more than 3 ******* SIM Swops on various of my mobile contract phones over the past 3 months. I am target for *****. Despite opening a police case and various complaints/ escalations Vodacom is not not able to resolve this issue. I have no confidence in Vodacom's security and ability to protect my personal information. I am now a target. My voluntary call limit was changed from R50 to R5000 without authorisation. A ***** target flag is on my profile but the ******* sim SWOPs continue. Where do I go from here???
