Changing premiums without notifying me.

To my disappointment my premium was double in Jan 2023, I enquired this with Discovery only to be told that in Oct 2022 they did not receive confirmation of my employment and therefore decided to increase my premium without notifying or having me agree to. Needless to say that they had an old email address and never once called me. When I took out this medical aid I advised them that I am no longer employed and wanted to cheapest cover just to be safe. Not once did anyone mention to my that I would be required to prove unemployment yearly. When an agent finally got back to me she requested that in order for my premiums to go back to normal and MAYBE I can get a refund for the extra premium that I will have to send bank statements and go and get an affidavit.

In what world is this ethical practice for unemployed people? to get them to use more money to prove that they don't have an income?

I enquired on canceling and she advised me that IF approved I MAY get a refund.

I have no words on how this baffles my mind, this makes me so angry.
