Cold calling, anti-POPI Act

Unsolicited, cold called, against POPI act. Hard selling. Initially asked if I am aware that a share trading account had been opened in my name by a financial institution. When I asked where they got my detail, story changed and they apparently got it from a "friend" who is a satisfied client. Could not tell me who the supposed friend is. I said I am not interested, still kept on "What are you not interested in?" I cut the call
