Shocking, Disgraceful and *********** service and customer care

After a ********** SMS received to request a Sim swop in January, Vodacom proceeded to approve this without my authorization and allowed the sim swop (Vodacom Security Systems/processes failure). I then subsequently received a statement on my RCI Makro account that reflected 2 unauthorized charges onto my Makro Credit account. I had to call Vodacom to re-instate my number and flag it to prevent this from happening again. This all started in January. RCI have now requested a sim swop report or a letter from Vodacom outlining the sim swop request to support my dispute claim for the charges on my account. I am not even in South Africa as I am on business in the UK for any of this. I have now sent 10 e mails Ref. (EC-1LST-2JN33N) and called every department that are willing to answer the phone, just to be told to call the Vodacom ***** department on *** (no answer for 3 days). The e mail *** also has not rep**** to any of my 10 emails Ref. (EC-1LST-2JN33N) sent over the last 3 weeks. Now, my question is, is there any organization/capability from Vodacom to attempt to resolve this request for their incompetence and lack of safety/security with my personal details (approving a sim swop without my consent)? How much more work do I need to do for Vodacom's incompetence to get a sim swop report/letter to supply my credit provider to get my dispute settled? Is the business that *********** to not be able to deal with a simple administrative request that they themselves are responsible for causing in the first place?
