Bestmed shares Private Information about their members to other members

I have asked for a statement for my time spent in hospital so that I can send that and the account from the hospital to my Gap cover. The agent sent me a report that contained ALL Bestmed members that was in that hospital for that time. So I have detailed information about three other patient's procedures and claims while in hospital. Surely this is a breach of Privacy? Then when I phoned back to tell them that this is not what I wanted and that I want the superviser's contact details they refuse to give it to me. The other person then sent me another audit report from the medicalaid but the amount there and the amount on the hospital statement is not the same. Then eventually after I insisted not to end the conversation without getting a superviser's name he looked at the document number and couldn't see that there were other patients names on it. So I told him to scroll to page 5 and then only he saw the other peoples names. I have main member names as well as the patients names and a detailed statement of their claims. So how many other people have received MY private and confidential information? This is unacceptable and I am not leaving it there. Especially now that the new privacy act is in place. Let's also mention that I had to spend 1 hour and 15 minutes to get this information. I eventually gave up on the PMB department for my other query as I was holding on for an excess of 15 minutes at a time.... What a joke!
