Receptionist attitude and condescending tone

The receptionist had an exceptionally condescending attitude when I queried regarding the payment of my appointment.

I explained that I attended a consultation with a GP end of 2025 and didnt have to make a payment as the consultation was covered by my medical aid and I have not since changed the plan.

She then proceeded to tell me in a rude and condescending tone and facial expression that that is IMPOSSIBLE because if you dont select a primary doctor with Discovery, the medical aid wont cover the consultation. I did not claim that she was wrong or that she is lying or anything of that nature. I was confused and merely asked a simple question. The attitude and tone was uncalled for. The problem is not the fact that there is an inconsistency with my medical aid cover. The problem is the receptionists tone and attitude. I was completely neutral and unemotional.

This is unprofessional behavior and unnecessary. I understand that a reception position is not a professional or prestigious position but I would expect neutral interactions with a receptionist and not an emotional one.

I will resolve the query with my medical aid.
