POPI act

Vodacom should stop sharing our numbers with third parties and violating the POPI act….I recently took a new line with Vodacom, the line is being used by my wife, but the contract is under my name, at no point have I used the number….only bodacom has that number under my name…my wife is getting calls from Elite Mobile amd other cellphone companies requesting to speak to me….this is a violation of my privacy, clearly someone at Vodacom is selling or sharing details
