Day light *******. Refusing to refund me from my OWN savings account

I went for an eye operation in May and received 2 separate bills for the procedure. 1 for the hospital and the 2nd one for the procedure. Discovery health only paid for the hospital and declined the 2nd claim of R13,500 for the procedure. I have resubmitted the claim more than 5 times but still call center staff would not give me a reason why claim is being declined, everytime I call i get a different agent who will then tell me to resubmit the claim.

The most annoying this is that I am on their classic comprehensive plan , which is the MOST expensive plan. I still have savings of over R14,000. MY OWN SAVINGS, MY OWN MONEY but this Medical aid decides not to refund me from my OWN SAVINGS.

The other thing is that I was using contact lenses but after the OP, I stopped using lenses and my eyesight is back 100%. Is that not a long term savings? Why is it difficult to refund me?

I'm so annoyed and ****ed off, I wish I had an option of changing to another medical aid
