Constantia Insurance / Prime Meridian shocker.

I took out a Prime Living Cover life insurance in 2015. I have been paying R1500 per month ever since. Now I have just been informed that the policy is being cancelled because of some change in the insurance act. I am approaching 70. This leaves me in a quandary of note. At what cost will I now get cover? At the time, I had a good insurance policy I had for twenty years, because the terms of this policy was better. What they have done is completely unconscionable and indeed shocking. At first, the cover was very low but it has steadily increased to the point where it now is well over R 4 million. I took the risk of low initial cover. Now, at this stage when it is finally paying off, they are pulling the plug because they found some loophole. I felt at ease knowing my wife would be cared for. Now this. Can this be? From a registered and reputable company I trusted? In their defence, they condescended to keep me covered until the end of April 2020! How generous of them. Their initial email contained this line: Please do not be alarmed, we will call you over the next few days to explain everything. Do not be alarmed?? Needless to say, no one called. They couldn't be bothered. What they are doing is certainly *********, if not *******.
