Horrible horrible service

Called momentum health on the 10th of June 2024 for a specialist visit authorisation, I was provided with an authorisation number then upon claim stage my claim is rejected and Wendy Nxele yesterday explains it was rejected because practice is not part of dsp and my benefits don’t include maxillofacial specilist. But then why am I suffering because of Momentum health’s incompetence? When I receive an auth number I did give the agent Ntombifuthi Mcunu the doctor s practice number. Why wasn’t I told then that I can’t go to this kind of specialist. Can you guys please pay my claim.
