Poor Service

Poor Service received from Discovery Health. I submitted a pre-authorisation request for the birth of my son, which was filled out by the Doctor and included the exact cost that he will be charging. I got an approval letter from Discovery stating that it has been approved. When it came to paying, they only paid a small portion of the total resulting in me having to pay the majority of it. Before this, I even called them and asked them the amount that they pay, and the agent said that they don't have specific amounts, which is the reason for the pre-authorisation. He said that if I get it pre-authorised, I will know exactly what it will cost me, which is clearly not the case. The letter clearly states that the procedure is Approved.
