Poor service - authorisation

My mother is on Keycare plus and had to have a huge operation done at an out of network hospital due to no other Dr being able to perform it. She was sent home with a PEG (feeding tube) as the operation affected her neck and mouth. The Dr who did her operation and inserted the PEG advised it could be removed on 06/07/22. On 05/07/22 discovery declined it stating it is a planned procedure - keep in mind that it resulted from the major operation required and the Dr that inserted the peg would obviously need to remove it. The hospital case manager stated she would motivate etc and call us with feedback. Just before 3pm we received an email and 1st page stated the authorisation number and it was dated for 05/07. We assumed it was for her procedure on 06/07 and the case manager didn't call back so we assumed all was fine. This turns out to be an approval for admission for my mom's admission 2 months ago - emailed to me 2 months later on the day we are waiting for an outcome???? My mom got admitted on the same authorisation number but was then unable to have her operation as apparently the authorisation was not approved. How can she have approval to insert a PEG but not remove it?? She has just been diagnosed with cancer, this has affected her emotionally and Discovery and Ethekwini Hospital have really added to her emotional distress. Pathetic service from both providers. We are now told to return to our gp to go through the whole process again while my mom can't remove a foreign object that's not in use, sit in her stomach. Julie Neuville ***
