Vodacom appears to ignore the ECT act and Popi act

Why does Vodacom insist on trying to find loopholes to manipulate customers. Their Vodabucks product (Which is a specifically separate loyalty programme) monitors user behaviour. I specifically have not opted in for this service. Yet Vodacom is yet again sending unwanted marketing, trying to trick me into signing up.

Getting proper confirmation that I am opted out from all marketing is like pulling teeth.

Maybe a class action lawsuit regarding privacy is just what Vodacom needs.
