I have phoned in to change my medical aid, I was help by an agent and asked the questions, that I wanted to know. I am on cronick medication so I asked of it will be coverred and that this is a Medical aid and not insurance, he confirmed it and said I can go to any dr and hospital, but when I went to get my medication, I was told ot is not a medical aid and have to pay. I was **** to and then I phoned in and there is a lot of stories now, I canccelled my medical with them and asked to be paid back my money, now they don't want to pay back my money, because I need to goe and buy my cronick medication, that I need urgently as I will get fits if I don't drink it, bit they don't care.
