Poor service delivery

My wife had an emergency C section due to an infection, she was kept two days extra in hospital and my son was kept in NICU for 14 days.<br> <br> He was born on 25/04 and I send his registration in on 29/04, he was however only registered in mid May by MOM. Due to the late registration doctors and hospital could not obtain autorisation for any procedures as there was no dependant code. Now there is huge issues due to no pre- authorisation being obtained....<br> <br> After various calls and emails of which I have the details I still receive unpaid or short paid bills without any feedback from MOM. I feel this is poor service delivery to have me spending time to sort out their fault. Some of the people were helpfull and did get some issues sorted but nobody takes control and says lets review all the claims related to this.
