General Waiting Period prevents payment for emergency healthcare

I've logged 3 separate claims with Discovery, all for emergency treatment given to my dependant. The claims were rejected by Discovery's pathetic auto-rejection policy, as my dependent had recently moved medical aids to ensure that she continues to get the treatment required for her condition,

We understand that there was a general waiting period as a result of the move, but my dependant has suffered from a Prescribed Minimum Benefit condition since she was a toddler , and needed emergency treatment after practically collapsing at work, as a result of this general waiting period restricting her from normal treatment

Since then, we've had endless communication logged with Discovery in this regard. After submitting all the documentation on 12 July 2018, I have not had any feedback from them. Every time I call them, my claims seem to disappear in the system. I have now received a final demand letter from the healthcare provider, and I am about to be blacklisted for non-payment.

Discovery, you have failed, and greatly disappointed me. What's the point of medical aid if it cannot cater for the people who have chronic conditions, waiting period or not?!?!
