A painful exercise dealing with Discovery to get a hospital account paid

This will be my second complaint that I am writing about Discovery, I had a PREMATURE baby, went into EARLY LaBOUR in Feb this year, they gave authorization to the hospital, but is rejecting the hospitals claims for the baby bieng in ICU and neonatal care, they are saying they need a report from the doctor for the babies stay in the hospital, the statement already shows what was done in icu to the baby, I dnt know what report they are wanting from the doctor, if it’s a motivation report than that is really ridiculous because just the fact that the baby was premature should already tell you why he was taken to ICU neonatal care, and the fact that they had given authorization, Trevor Richard has been assisting me but one cant call him, they refuse to put you through to him and he ignores my emails asking him to call me, between Flora hospital and Discovery I am really tired of dealing with them to get the account paid, this really is a painful exercise, niether of them is willing to assist to make this issue easy, I should be enjoying my baby but I am begging both Life Flora and Discovery to talk to each other to sort out the account,
