Worst Medical Aid EVER!!!!

I need to vent my frustration with Sizwe medical scheme. When I joined I was placed under a waiting period for my thyriod, which is understandable. In February this year I was admitted to hospital due to complications with my pregnancy. While in hospital the doctor tested my thyriod for good measure but I was not admitted for my thyriod. So logic stands to reason Sizwe can reject the blood test based on the waiting period but still pay the hospitalisation which had nothing to do with my thyriod. Apparently Sizwe does not possess this logic. The overall bill is just over R7000 for the hospitalisation. Best of all at that time I was paying well over R9000 every month which is more than the hospital bill. I have fighting this issue since I received an account from the hospital in July. Still NO PAYMENT, NO SERVICE!!!!
