MiWay breaking the POPI ACT and regulations

MiWay making ******* sales calls that go against the Consumer Protection of Information Act (POPI) Act. I al sick and tired of getting sales calls from MiWay Insurance, I don't even own a car - but they call me every other week. When I ask the lady, where do you get my contact details from, they just get become rude, drop the call on you and tell you "well if you are not interested in taking out insurance, that is fine" The point is not that I am not interested in insurance, YES that may be true - the point is - WHERE DO YOU GET MY DETAILS FROM. Because I have a right to know and remove my details from there, so I don't get another call from your colleague next week again selling me the same thing. As soon as she drops the call, the number just gets recycled and next week its another colleague calling from the same contact centre. I mean, this need to STOP. What MiWay is doing is *******, according to the laws of the country in 2020 - If i had the time, I should record these calls and see you in court - how about you just remove my details from your ******* call list. I never agreed to be called by MiWay or any other company for sales purposes, I have not opened an account in years and do not even own a car, nor have had insurance in over 5years.
