Discovery Health, disgusting customer service

I went to local hospital emergency. The Dr on duty advised i stay overnight for monitoring and medicating. I was stable by morning, so was discharged. In my opinion the Busamed Hillcrest hospital staff were great and did the right thing. Now Discovery Health are rejecting the claim. The reason given is because my medication was oral I should not have stayed in the hospital but should have gone home. So a claims clerk decides and overrides a medical Dr's decision 🙄. How could I be monitored overnight if I went home , unbelievable. I have tried numerous times to contact Discovery. Just end up hanging on for ours in the digital call center. Finally I got thru to Zama, Case manager, who just threw Discovery policy at me and would not listen to or consider my situation. When I asked to talk to someone higher up the ranks, then she just put the phone down while I was talking. Absolutely incapable and disgusting service. After almost 30yrs as a member this how you get treated 😡🤬
