Discovery Pre-authorisation turn around more important than treatment of a partial amputation wound

So on the 23 July I had a further partial amputation of my foot which now requires wound care. The wound clinic that I need to go to requires a cash payment after treatment. Treatments range from R2000 to R3000. The wound clinic is required to motivate visits and treatment. When I had heard nothing from Discovery I phoned the pre authorisation they stated that they cannot help me because the turn around time had not happened yet. So apparently I need to bleed and get a septic wound while I wait 3 to 5 working days for the turn around to happen. I cannot get treatment now because I cannot afford to pay cash. Surely there must be exceptions and an escalation could take place. Thanks Discovery sit there waiting for the claim to turn around while I lose blood.
