Absa Activate insurance

My review is on Absa Activate, a sub category of Absa Bank. I recently moved and when I wanted to change my address, I was informed they can no longer cover my household contents as I am renting a flatlet and main house must be a client before I can be insured. This, after I've been with them for few months already. How is it possible that my Lessor must be covered with them, in order for me, the Lessee, to be covered? After various phone calls, without anyone answering and various emails, no reply was received. They just cancelled my house contents and refuse to explain or answer my emails.
