Pathetic Discovery Health Call Centre

I am highly frustrated with Discovery Health (PTY) LTD who are the administrators for the Discovery Health Medical Scheme. I have tried to use the self help channels, and in my opinion they are not comprehensive enough ! The specific documents or explanations or rather explanatory notes are not available on any mobile app or the website. I tried to contact the call centre and after listening to about 3 minutes of unnecessary information there was an automated message saying I will be transferred to the next available agent, only to have another message saying "this mailbox is full" and then the call terminates ! If as an administrator there is no capability to manage members, kindly let me know so I can contact the CMS and officially lodge a complaint. I don't have the time or energy any more to get frustrated while paying for a service that is not delivered....No doubt after this review I will get a call to apologise, but I will bet my last cent that in the name of so called efficiency the problem will persist, I actually pity members without a smart phone and data or wifi, who will assist them....
