Discovery Health - Kickbacks?

My daughter went for wisdom teeth extraction on 27th April. I called Discovery and went through process to obtain authorisation and explained that the Maxilofacial surgeon indicated that they are a private practice and I should pay the full account ahead of the surgery or she will not be admitted. I was advised by Discovery call agent that I should just submit the statement from the Dr and it will be processed. This is what I did and Discovery then loaded a payment for the surgeon of just under R8000 instead of refunding me. On query (***) I was told that I (the customer) should now log a query with the claims adjustment department for the payment to be reversed and paid to me. I did this. They then refunded me only R3450. When I queried this and spoke to Noba Kolisi (call centre manager) I was told that they paid me 100% Discovery rates but paid the surgeon according to their "arrangement" They also did not originally pay me, even though I submitted a zero balance statement of account, because the statement did not state "paid by patient" The instructions and feedback is not consistent as Discovery's call centre agents never once gave me the full details or advised on any of the things mentioned above. In the end I am out of pocket but if I had left it and rather asked the surgeon to refund me I would have received the full amount.
