I will leave Discovery because of this

My sister lives with me, I take care of her, she is like my child.... I want to add her to my medical aid with YOU but you declined because there is no legal documents from the court. My mother signed that she lives with me, but this is not good enough!!! My mother has no income and no medical aid, so HOW is my sister suppose to protect herself in the case of a medical emergency??? What respectable company would deny a child medical aid???!!!??? I have been with you for years, but you have let me down when I needed you!
