Bad service

I'm so disappointed with Umvuzo medical scheme and I want this matter to be reviewed. My daughter changed her medical aid from her previous to mine(Imvuso). She has been on her previous medical aid since she was born and decided to change to mine in January. She is turning 13yrs in May. I was shocked to hear that she needs to wait for 3months in order for her benefits to kicks in. We have produced the certificate for her previous medical aid. What shocked most is their consultants are not well informed because they are giving me different stories. I called several times being told that it is possible for her medical aid to be active immediately. I was actually advised by one of their own to speak to my HR to ask medical aid scheme to activate her benefits immediately however now I'm running pillar to post. They told me all the requirements I need in order for her to qualify her benefits immediately.
