Poor service under extreme medical condition

I was with Dicovery Health for years, lost my job and had to cancel my insurance but rejoined as soon as I could. I was then penalized for a 12 months waiting period for previous conditions because of late joining.

Recently I've been diagnosed with F4 Liver cirrhosis of which the Doctor had to do a life threatening test (Bone Marrow Biopsy) and discovery refused to pay anything even though it falls under PMB (Prescribed Medical Benefits).

After numerous emails I sent to the Doctor with the correct coding they still refused and say I'm in the waiting period. A dispute was made and it's now day 5 with still no reply from Dicovery regarding the treatment I must undergo for a gastroscopy for varicose veins that could burst at any time but this does not seem to be a concern of Discovery - Pieter Mc Master
