I keep receiving calls from a variety of (02) and (03) numbers over the past couple weeks. Generally they hang up without leaving a message. When I have answered, they call me by name and say they are from an online investment group. I've repeatedly asked for my details to be removed from their data base but they refuse to acknowledge my request, saying "why?" When I say I'm not interested they reply with "how do you know you're not interested?" We just go round in circles until I hang up. I've received these calls from well around 20 different numbers.

Caller: "White" something

Constantly calling on different numbers based with Sydney and at times Melbourne area codes.
Has to do with online money making.
My consistent requests to remove my number and name from their data base gets ignored. Caller continues to all why I want my details removed and why I'm not interested in making money. I eventually hang up because this conversation just guess round in circles.
