POPIA Act being transgressed

I was contacted by a company EliteMobile claiming to be Vodacom for upgrade. They had all my information including Bank account. After a long discussion on the fact that Vodacom had transgressed the POPIA Act by giving out their Database to another company I was once again told they Vodacom. I did an upgrade which would cost R150. This was all fine until I have now seen my Bank account being charged this R150 every month. Vodacom says it is EliteMobile and they again blame Vodacom for someone in their Accounts department deducting the money every month. I have managed to reverse this last month's deductions but we will see how long it takes to get my other deductions back.
