In contravention of POPIA Act and ignoring request to remove personal information

If I could give a 0, I would have. They keep calling me to sell me products. I've told them multiple times to remove my number from their system as I never gave them permission to store it. I don't own any 1Life products and have never requested a quote from them before where I could have provided my information, so they've obviously purchased the information from a 3rd party, which is ******* as per the POPIA Act.
