Disappointing Service

I called a week in advance and asked the receptionist whether they take medical aid. I explained that the funds I have will not cover the consultation, she reassured me that they will put a claim through to my medical aid (Bonitas) and the difference can be made in cash thereafter. I asked whether I need to contact the medical aid, she specifically said that it's not necessary and they will do so. Today, we drove to the doctors’ room (we live 2 hour drive away). Upon arriving, the reception then said that they don’t deal with medical aids directly, and that only I or my GP can get medical aid authorization. I asked the receptionist to allow me the use of their office phone to call my medical aid or doctor to get the necessary authorization, to which she refused. She told me that I can’t use their phone because she needs to “keep the line open”. It's the first time that I've been to a doctors’ room with receptionists who aren't helpful and don't help patients who are not very knowledgeable about these processes and terms. Seems like this practice aims at receiving cash only patients. Their only aim is to get their money with as little effort as possible including not wanting to deal with the medical aid. They are not considerate and do not help or educate patients whom are on medical aid. Receptionists are rude, unfriendly, give patients the wrong info and have a don't care attitude. The doctor in question, whom I have not had any interaction with, should seriously consider the manner in which his staff deal with patients. This is probably the worst experience I have ever had in dealing with a medical practitioner. I will certainly never go to them again, as well as inform friends, family and my GP of this poor service.
