Discovery - No concern for customers (Change of DEB policy with no clear information)

I have had enough with Discovery. I have tried contacting their consultants. I have sent emails and I still seem to get no concrete answers relating to my below concern:

I visited a GP with which I checked on the MaPs tool prior to the visit as I had run out of MSA savings - this is a GP which I have gone to for three years. This tool clearly shows I am fully covered on the network with DEB, provided I have consultation visits available, which I do.

I have sent numerous screen shots to consultants and yet I seem to get automated answers (pre-prepared responses where ones concerns are not addressed, but rather why they cannot help me).

Discovery has now turned around and told me that they do not cover this particular GP when their MaPs tool quite clearly shows they do. How is one supposed to visit a GP and be covered when the information provided to customers is clearly incorrect/not clear.

If this is not rectified I will be changing my Medical Aid scheme. It seems Discovery has changed their tone with customers. I once entrusted their services but my faith is slowly dwindling.
