Issues with Justified payouts

When I signed up for Medical Aid near the end of last year. I agreed to be debited a certain amount. My last 3 debit orders have over charged me, way more than I signed on for without notice of a fee change.

Not only that, after I got out of that waiting period nonsense so I could actually use the service I pay for every month, it was fine for 1 doctors visit. Now in 2018, not even 2 months in, after all debit orders. I had to go to my GP for a cold, so all good and well I went, got checked up, prescribed meds and antibiotics, which was covered on collection by Medical aid.

Today, I get an email from my GP stating the following:

"Good Day Brandon

Please see attached account statement. The claim we sent through to your medical aid for your consultation on 08/11/2017 was rejected by Discovery because you were still in your waiting period. "

What is this!? We have moved out and ended the waiting period for months now. And for some stupid reason they are refusing to cover a R128 visit!

This is unacceptable, I have put up with the over charged debit orders, but failing to provide the service I PAY FOR EVERY MONTH is just bull****.

How can you claim to offer Medical Aid and not provide when its warranted and viable.
