WORST WORST CLIENT SERVICE FROM DISCOVERY MEDICAL AID. TAKING MONEY!

I joined Discovery medical aid in 2018/19. The time when I was still an au pair. Since then they never asked me for a pay slip. Last year September/ )ctober 2023 they asked me my pay slip and I gave it to them. Never heard back from them to tell me what my new premium will be. On the 28th of December 2023 I got a sms saying my new premium will be R8500. More than double of my previous premium. Saying it will be deducted on the 2nd of January 2024. They did not give me any notice or tried to call me asking if that was ok, or whether I could afford it. They have my pay slip in front of them. How can they THINK that I can afford that. I called them on the 29th of December to stop my medical aid. I spoke to Olwethu Fezeka Dube. She didn't even try to keep me as a client or offered me better deals. I knew my premium will go up but NOT WITH DOUBLE THE AMOUNT!!!! NO NOTICE GIVEN! She told me that I have to give a months notice. WHERE WAS DISCOVERIES NOTICE??????? AND I AM NOT THE ONLY PERSON THEY DID IT WITH!!!!! ARE YOU TRYING TO GET A MASSIVE AMOUNT OF YOUR CLIENTS???????? I am furious! I stopped the debit order at my bank, because I did not authorize that amount! I did not make use of Discovery in January. Now on the 2nd of February they take the amount again. AFTER i cancelled my membership on the 29th of December. After how many emails sent, no one comes back to me! No one calls me. Reference umber: *** Someone better get back to me! I am a teacher, 2 kids, unemployed husband. They knew this. How can they expect me to afford that premium. That is more than half of my salary. Pathetic
