Discovery is delaying my payment

On 7 November Discovery agreed to settle my medical bill with the hospital and the doctors but until today no payment was made. I have been making a follow-up with this payment for the past two weeks with no help from any of their consultants. I'm now getting told that the agent needs to make adjustments from the amounts claimed yet when their agent called me she told me that they will pay the whole amount. I have been requesting to speak to their agent directly (Kajal) and got told that they are not allowed to give out their numbers but during the time of getting them resolve the claims issue they managed to put me to her directly. This is so frustrating because the hospital is calling and sending me smss everyday as their payment is strictly 30 days from service date. I don't even understand why they suddenly changed the amount claims yet they agreed to pay the whole amount when they called me. T'm very frustrated because this issue has been going on for over a month now and its exhausting.
