Discovery life representative promises to make me a millionaire and shames my salary

I received a call from a discovery representative on this number ********** at 17:16 on the 15th of May 2019 ,she was trying to sell me a discovery life policy that she says it is not meant to replace my existing life cover rather it adds a cash back benefit to which ever life policy that I have.She said I will get cash back every four years after I turn 65. I immediately told her i am not interested,she kept insisting,she was unprofessional telling me she had a long day.She became desperate and started making unrealistic promises.She asked me "don't you not want to be a millionaire ?" " i am giving you an opportunity to be a millionaire " , Well i want to be a millionaire but i don't think there's any discovery life policy that is designed to make people millionaires. She kept nagging then the conversation went sour when she asked me for my gross salary i asked her what does that have to do with life cover,she said that's how they assess the risk, when I eventually told her my gross I was then insulted,She asked me why was I afraid to share my salary they get costumers with way higher salaries and they give away their salaries information easy. I told her I don't care about other people, I just didn't want to share mine,then she said "we have your ID number we have your cell number we could use it to do anything" (We as in her and discovery life,i guess). What kind of people represent discovery life? Why threaten me with my personal information that i don't even know how they got hold of? if calls are really recorded i recommend discovery life to go and just listen to that phone call just to get an idea of what promises and statement your representatives make on your behalf.
