Worst service ever

I asked Hollard a simple thing that I prefer receiving communication via email not post as anyone can open the letters. More especially because where I stay I do not have a private post and they just put those letters at the gate. They information Hollard sends has got my private information and ID numbers. What happened to following POPI Act. Do I really need to cancel my policy because my wish can not be respected. I was told to send an email to the complains department and it has been 2 weeks now without feedback
