Changing from Balance to Full Vitality

I recently joined on of the medical aid , that puts me automatically into the Balance plan for Discovery Vitality . Last week I then phoned in to change this to full vitality . I received the email about this confirmation for FULL Vitality and also the amount that will be billed. When I was trying to join Virgin Active , was told I am still under the Balance plan. I then phoned Discovery Vitality about this , the Consultant I was talking to , said they will sync it immediately and in an hour it will be fine . I then go to Virgin Active to join . Same situation STILL under Balance . I phone again Discovery Vitality , the Consultant says they will give the matter to the Sales Team to handle and they will come back to me same Day . Following Day I go again to Virgin Active same thing I am still under Balance plan , even though I am suppose to be under full vitality . So how much , how long , I have to call , to get the most basic services I actually bought to come my way.
