Discovery is so unhelpful in this time

i had a new born baby on the 19.08.2021 which we added him to my medical aid not so long after. The doctors started submitting claims through and discovery decided to take this all from my medical savings. which obviously is not enough so they started rejecting payments. i dont know how dumb that is because im sure they have added new borns to a medical aid before. i called in and got a long story from a lady telling me about getting authorisations and so on and it will all be sorted out but to date still not all sorted out. when i called in a week or two ago, spoke to another lady and she advised me that there was doctors submiting these wrong, but they were still accepting and just taking it from my medical savings. No one is helping me figure out which doctors or bills were being submitted wrong or assisting to query this with the doctors, they just telling me it is not there responsibility. This is the worst service i received from them, i mean i must sit with a sick new born and get calls and invoices from doctors saying i owe them and i am paying medical aid. i am shocked that they would take from my savings having done these things before, and if receiving wrong documents, dont bother even querying this with the doctors. this is pathetic and i want this sorted out. this is supposed to be Discoverys daily job, not mine.
