POPI Breach | Personal Information used without consent

The Matrix Tracking call center contacted me to sell me a tracking solution. Upon me asking them where and how they obtained my contact details and information, the agent declined to confirm where they got my information from. When I told the agent that I have never been a Matrix client and would like to know where they got my information, he declined to provide and answer and as professional as a call center gentleman he is, dropped the call on me!

I don't think that is the way Matrix should be treating any of its existing and potential new clients, it was very unprofessional and I still feel I deserve to know where my information was obtained and have it removed as I did not give consent.
