SPAM - won't let you opt out!

Won't start spamming me to sell life insurance. The opt out option does not work. I have never dealt with Hollard Insurance in any capacity, and they do not have my permission to use my details. I was registered with the national opt before they started to spam and therefore have no right to contact me. They have no consideration or respect of the POPI act and will be reported to the DMASA if they continue to spam me.
