Spam SMS's and can't tell where they got info from

I receive SMS's from 1Life and I never had anything to do with them so I don't know where they got my PERSONAL INFORMATION from. <br> <br> When I rep**** YES on one of the SMS's, the agent could not give me straight answers as to where they got my information from. I was told that it is from the \Consumer Database of South Africa"but could not tell me how I can contact this company or a name of the organisation compiling these databases or how to remove my personal information from this database.<br> <br> My name has been removed from their database but I am concerned about WHERE they got my information FROM. Where is the proof that I consented to any marketing? Wondering if this method of marketing complies with POPI?"""
