Unpaid medical bills

On liberty hospital select with a gap cover. Gave birth 3 months ago, and my gynea has not yet been paid via the medical scheme , I also asked permission to have him at Constantia medi clinic as this is where my gynea is situated but was not on my \panel of hospitals\" and the admission got approved, but no where did it say I had to pay R8000 admission fee, as I was told my GAP cover would cover this. So I am sitting with a unpaid gynea bill, a u paid R8000 admission fee and on top of it my little boy landed up in hospital two weeks later and he was added as a beneficiary on my medical scheme and all of his in hospital pathcare accounts of +-R4000 have bounced back. Very disappointed and have no idea why I pay so much for such bad service "
