Incompetence, poor communication and misleading advise

I considered to move to Discovery and consulted with a broker. My only condition to consider the move was if the benefits would be the same as with the current medical aid I was on. My broker was aware of my chronic condition and promised that Discovery will pay for my chronic medication even from the start, there will thus be no waiting period for payment of my chronic medication. I was also told, that the broker has patients on the same plan who uses the same medication, and it being paid for by Discovery. Two and a half months later I have no idea what is the way forward. Currently I am financing my chronic medication out of pocket for which I have not budgeted for. It seems that once you have joined Discovery, your problem is your problem and the feedback is silent.
