Pathetic service and untrained staff

I'm utterly disappointed at Discovery health, I have called the call center to explain exactly what I was experiencing and the call center lady assured me that my plan would cover me. Before getting admitted I received an email with my approval number. After getting discharged I received a letter stating that discovery will be reversing my approval based on a medical exclusion yet I got telephonic confirmation that I would be covered.

Are several emails and calls to Discovery, no apology has been made to say that their untrained staff gave me the wrong information. If they gave me the correct information I would never have been in this position in the first place and secondly I received approval before I got admitted, I wouldn't have admitted myself if I knew I was not covered. With the amount of money I've been paying for my medical aid every month. I could have paid for my unpaid bills.
