Incompetence on providing Authorization in time

I had breast cancer and need to undergo my reconstruction surgery. My doctor sent the motivation letter with all the relevant ICD codes and supporting documents on the 26th of November 2017, in order to obtain the Authorization number from Bonitas. Since then, me and my husband is phoning Bonitas every day to find out how far they are. Both of us had to put in leave for this surgery as it is in Pretoria and we are in North-West. Bonitas only woke up on Wednesday the 6th of December 2017 and saw that nothing was done from their side to obtain the Authorization number. My admission date is the 12th of December 2017 and my Doctor needs the number urgently in order to book the facilities. Bonitas even admitted that they delayed the process from their side and that they are sorry. Fact is, sorry is not going to help. I need to obtain that number today in order to undergo my surgery on the 12th. This is absolutely unacceptable!!!!!
