Vodacom Sharing PERSONAL Information without consent !

I received a call today from Rewardsco - i guess they are outsourced by Vodacom since they told me they are phoning on behalf of Vodacom, the number i was called from ***, they wanted to upgrade my contract - WHY am i upset ? well we have a POPIA act that prevents sharing of personal information to 3rd parties without consent , so i am going to cancel my contracts (4x) with Vodacom and open a case with breach of contract with my attorneys and im going to sue Vodacom for a lot of money,

This company had access to my personal information like ID number, Banking Details and address _ so this was the straw that broke the camel's back Vodacom Please feel free for your legal department to contact me on *** to remedy this before we are opening a complaint with ICASA
