I have savings and they will not let me spend it on a doctor's script

I went to Dischem Woodmead, and went to the pharmacy for my script. When the pharmacist entered the details the item came up as an "exclusion". Bonitas/Medscheme were called and Oledeng answered. I asked why I was not allowed to spend my money on a doctor's script. Oledeng said that he would refer the matter and the response would take 2 to 5 days. I asked to speak to the supervisor and had to hang up as I was holding up the queue. I went back home and called Bonitas/Medscheme and spoke to an agent who then put me through to supervisor Margaret Maibi. When I was not happy with the same response, I asked for the next person up. This was just after 16h00. Jean-Marie Lange had gone home. The next person up, Mr Raphael had gone home. After some berating I eventually got the phone number for the General Manager, Mr. Lee. I called and the phone went straight to Voice Mail for Pippa(?). Left a message. I wait for an email from Margaret tomorrow morning before 09h00 from Margaret and a call from Pippa in the morning
