Shocked by steep hike in premium

I RECEIVED notification from my insurance company that the premium for my medical insurance had been revised. I had expected this because of my age, 65, but not the quantum of the increase. The revised premium for 66 years old was RM7,795, but what I got was RM13,407, which is simply exorbitant!

I know PIAM (General Insurance Association of Malaysia) allows the revision, but the quantum is quite shocking. I wonder whether these increases have been approved by PIAM and Bank Negara Malaysia.
