Quick to take your money but claims rejected on spurious and nonsensical grounds

This is a follow up to an existing complaint. Discovery refused to pay the lab for a respiratory panel test claiming that a respiratory panel (which tests for things like Covid) can ONLY be ordered by a specialist, meaning if you suspect you have Covid or even the flu you have to be referred by your GP to a Specialist so Discovery can incur the additional expense of a specialist to order blood tests. Absolute idiocy. They promised to escalate, blah, blah blah and it would take 3-5 days. Well it's been 10 days and nothing is happening. I have since investigated and found that this is the only respiratory panel test they have rejected. A measure of any company is the quality of after sales service. They have none. Not too worry Discovery, I'll pay it but know that I'm shopping for a new medical aid.
