Vitality - No one is trained enough to assist me

I have been on Discovery Health Medical Aid for over 5 years with the added benefit of Vitality. I changed jobs and discovery cannot do a simple thing like adding vitality to my existing medical option. Instead I have received countless emails asking for confirmation of my banking details which I have sent through. Its been weeks now and still I am no closer to joy even after communicating with a "manager".

Highly frustrating Regards Estelle Thomas
