Unhappy Pensioner member

We are on the Key Care Plan. I, dependant 01, arranged an appointment to see Dr Bosman (Dentsit) for toothache. He is a Network Dr. The consultation was rejected. The lady at his accounts department explained that the Doctor did not performs a procedure but the consultation did took place on 12/12/2018, which becomes now our responsibility. My wife who had the treatment, questioned the medical aid. According to us: either the Doctor must lie and use another code to get the claim paid by Discovery or let us as a pensioner member be liable for a service rendered. How can the medical aid accept all consultations, submitted by a GP if they also just do some checking and claim a consultation. The prescription is at the end the treatment that will help you get better!. Please re-consider or discuss this for future to be accepted as a benefit to us on this specific plan. We need the basic service and that is why we have selected this plan. Please consider the hisitorical medical condition I suffers from, we cannot go to a lower plan and due to affordability, we cannot go to a higher plan. We do not misuse our medical aid, and need this to be revised please!
