Disappointed, angry and scared for my health

I have been on the phone with Discovery PMB department everyday for the past 4 days. I have an urgent admission into a hospital - however, this cannot go ahead as Discovery 1) Did not accept my out-patient PMB application in full and thus I am missing 6 PMB days and as such, I cannot be admitted which is putting my health in danger. 2) Every day, I am pawned off to another consultant who have said it has been escalated and have PROMISED that the relevant person will be in contact will me - I HAVE NOT RECEIVED ONE PHONE CALL FROM ANYONE AT DISCOVERY FOR PARTIAL OR FULL FEEDBACK. This is a seriously urgent matter and I feel extremely let down by Discovery.
