Bad Bad BAD Service

My daughter took an overdose on the 17th of December 2020. We rushed her to hospital. She was in casualties where they treated her. After 1 o'clock on the 18th they got a bed for her in ICU. The authorization number is now from the 18th which resulted in my medical scheme Bonitas not paying a lot of the doctors and lab invoices. I have contacted Linksfield on numerous occasions and was told that the Case Manager need to update the auth number to the 17th. Up to now it has not been done. I have asked several times for the contact details of the Case Manager - but according to them I can't contact her as they have their channels. Clearly those channels aren't working and will result in Linksfield Hospital and Lancet Laboratories to sue me for the money as clearly someone is not capable of doing their job and do I really need to pay the price for incompetency of Linksfield accounts department staff??
