Vodacom *****ing money with ********** actions

A problem with Vodacom.

VODACOM placed an ******* cell phone contract belonging to somebody else onto my account. They ran up a bill into the thousands and VODACOM took money out my bank account. This problem was addressed by the VODACOM ***** department and it appeared to be sorted. I will never know if the VODACOM staff member who committed the ***** will ever be taken to task and charged. I did have all that relevant information in the documents sent to VODACOM ***** department. I was told by the ***** squad person on the other side of the phone that this was not my concern as it was an internal affair.

All this was well until the 2nd of January 2018 when VODACOM once again debited my account with the same cell phone number usage details and stole thousands of rands again.

As a single person against VODACOM, where do I stand and how do I prevent this blatant theft from happening in the future?

I will be cancelling all my VODACOM accounts as soon as this bull**** is sorted.

How did this all happen with all the required documents needed? Proof of residence and FICA etc ??
