Misleading information given by consultant

Having recently joined Bonitas medical aid, I called in to ask if I need authorisation for my autho treatment and chronic treatment which I am undergoing. The consultant responded by saying I don't need any and that I only need to submit my claims which will be processed. From that response my chronic claims were submitted and to my suprise were deducted against my savings. When I called in to follow up when my savings were being depleted I was advised that I need to submit a letter from the doctor, which I did. They refused to backdate the treatment saying it was only approved when I sent through the doctor's letter. I explained to them that the reason for my not sending any form of communication before was because I was advised by their consultant that I need not. They advised they'd listen to all my call recordings and they called the following day to say none of them have any queries on pre-authorisation. I asked for the tapes to be sent to me and I was told it is not possible. I am now being sent back and forth between the Johannesburg people and the Cape Town branch. Can I get value for my contribution?
