Hospital claim not paid and it's been 3 months.

I was hospitalised in November and the medical aid authorised and then declined my stay moments later. Then they made it my problem to gather doctor information while the hospital was harassing us for payment. I then had to pay 20 000 rands out of my own pocket. The hospital is part of their chosen hospital networks. Till this day my money has not been refunded. They are unprofessional and ********* yet I pay them 5.5k ontime every month. When I called today the want to shortpay my claim by 2000 uet this is one of their network hospitals. This is not right and will also be escalated to the health ombudsmen. I urge and ask all South Africans thinking of joining Bonitas not to do so. You will be left in debr while paying them. I want my full refund as this is their hospital network choice.
