No human element, just systems doing the opposite of what we need!!!

So a certain provider clearly told us that she does not accept medical aid and that we pay directly to her then claim back from our medical aid, and we did do. She sent us the invoice and we loaded the claim on the app only for discovery to pay the same person that has told us that she does not accept direct medical aid. I was told “it’s the system that automatically does this” what kind of a systems is that, that allows patients to claim on behalf of providers??? Why would I log a claim for a provider? Why does the system not know the providers that do not take medical aid?? Right now I’m seating with an inconvenience and discovery is not even sorry at all. In the past I was able to claim for the same provider then they changed the system to be in a such a way that it allows patients to claim on behalf of the dr’s and providers. What kind of an upgrade is that??? I need to know how discovery is gonna make sure this will not happen anymore because I will still use this provider over and over again!!!
