No Covid test cover from Sisonke Medical Aid. Disgusted!

All other medical aids cover Covid 19 tests, whether it is for pre-authorized for hospital admissions of covid related. I have n heart condition of which i need a angiogram for my active angina. I need to postpone surgery cause Sisonke informed me that they do not cover covid tests not related to covid 19.. as this is the hospitals who demands tests to be admitted. So, please explain... if i die of a heart attack or get sicker it is okay cause its not worse than covid, so you pay your own test as its not serious... only covid related tests will be covered if positive cause only covid matters? Medihelp for example sms members saying memebers are top priority to them and will cover all covid tests surgery related or covid related.. they are looking after their members where Sisonke jyst dont care at all! I dont have R900 to pay for a test just to undergo a serious matter... Sisonke is bad and robbing us... Who funded medical aids to cover all vovid tests... so i need assistance here please! I cant go for my cardiology related procedure cause its not life threatning according to sisonke... we pay a lot for medical aid just to receive provincial hospital treatment! Disgusted once again!!!! Momentum also (sisonke powered by momentum) covers covid 19 tests.. sisonke is bad really bad they dont care about their members at all!!! Im very sick and now need to postpone procedure to get money for a test... DUE TO them not paying tests i live on the risk zone!
