AllLife Life insurance - bunch of ****mers and *******

I had heart failure in 2020. I have recovered so well that I am down from 7 pills per day, to only my blood pressure meds as well as Carloc that I take for my heart. Since All Life offers Life policies to people who had heart attacks, diabetes, HIV, etc, I contacted them for a quote. At first they were very friendly hand helpful, and gave me a policy for R3million, at an installment of R1200 (Aprox). 2 and a half month went by with no issues, and then the nurse came to take my blood pressure and blood test at home. a few days later they phoned me to inform me that my cover is now only R1million and my premium has doubled, AND there is a 5 year waiting period???????? I was hesitant at first, but later agreed. Then they sent me a letter that my policy has been cancelled???????????????????????????????????? I have sent numerous emails with NO communication form them??????????????? I will NOT leave this here. I will go to every social platform imaginable
