Penalized for Discovery Error...

Due to the fact that my medical savings was depleted, I consulted the Discovery website and spoke to a consultant about accessing one of my additional benefits; the Day-to-Day Extender Benefit, which allows me to receive General Medical Practitioner service from listed network GP's. According to the list, Dr Louis Muller, from Vredenburg, was listed as a part of this network. For this reason i then made an appointment and went for consultation. At the end of the consultation, the administrator requested that I make a cash payment, as the claim had been rejected, due to the fact that there is a discrepancy with Dr Louis Muller's practice number. I personally felt that this was not my fault, and the matter should be resolved by the concerning parties. I paid the consultation, and the follow up I made to Dr L Muller, as I had a reaction to one of he medications i received. The total paid was R 1170.89. Once back at the office, I called Discovery to find out whether or not i was allowed to claim for a refund from the scheme as the administrative discrepancy was not my fault, and according to the setup, the claim was supposed to be covered as I consulted a listed Day-to-Day Extender Network GP. The consultants that assisted me over the phone was very unhelpful as they took a look at the proof i submitted, and said that I could not claim for this, and the reason for the claim being rejected was due to the fact that the practice number for Dr Louis Muller is incorrect... I told the consultant, that as we speak, Dr Louis Muller is still listed as a Day-to-Day Extender Network GP.... My question is this... Why should I be penalized for a error that I clearly had NO control over? I did not make the error with the practice numbers... I did not list Dr L Muller as a Day-to-Day Extender Network GP...
