Discovery Customer Service Sucks

I joined Discovery this month because it is the preferred medical aid of my employers, after completing my application and being accepted as a new member I was told that I would have to serve a 12 month waiting period for my chronic medication. I was told that I needed to lodge an enquiry to have this matter investigated since I had already served a 12 month waiting period with Key Health. They asked me to submit the medical aid certificate showing that I had served the waiting period and I sent it to them and I was told that my case will take 2-3 days. A week later when I called to find out what the outcome was I was told that they did not get my documents. I them resent the documents I sent the previous week but for some reason their system was not generating a reference number for me as it was supposed to and the agent kept telling me that I haven't sent my documents. After countless tries I eventually got the reference number and was told to wait 2-3 more days for an out come. They most frustrating thing about this is that the agent was not willing to understand my frustration, to him, I was not sending the documents. He made me feel like I do not know what I am talking about and did not care what happened to my previous enquiry. This for me was very poor customer service from a market leader who proclaim to be the best in the business. My advise... STAY AWAY FROM THEM!
