No Confidentiality - violation of the constitution

I have requested a letter or a confirmation of membership from Fedhealth. The one that you can self-download from their website it specify a whole lot of information including your contributions and your medical health status. One consultant (Michael) told me that is for my eyes only but I told him the one I need , I want to sent it somewhere else he promised to send it with the exclusion of my medical history.

I phoned Fedhealth again explaining the above, this time with Antonette, she told me those confirmation of membership letters are generated by the system she won't be able to change that. She can only draft a letter that specify the joining dates and my contribution.

My question is does Fedhealth has a right to do that on their system. Where is confidentiality and the privacy of the clients or of patients?

Or they are above the law when it comes Privacy and Confidentiality of patients that binds even medical practitioners?

(3.1 The National Health Act (Act No. 61 of 2003) states that all patients have a right to confidentiality and this is consistent with the right to privacy in the South African Constitution (Act No. 108 of 1996).May 30, 2007)

Please advice.

Thank you
