Bonitas Bad Service

I was hospitalized in previous weeks and the doctors were supposed to perform a gastroscope but the medical aid said it does not cover the doctor who was supposed to perform the procedure even though Bonitas chose the hospital. After I was discharged and I called Bonitas to let me know which doctor do they cover, I also sent them an email on the 13th of November 2021 with all of the information they requested from me. Yesterday I got a call from the doctor telling me he has booked me for the gastroscope for Thursday 25th of November 2021 and since I received no response to my email from Bonitas, I called them yesterday and the agent told me she is going to put me through to the Authorization Department only to be put through to an automated menu that required me to put in an extension number that I did not even know and after calling back again to inform her that she put me through to an automated menu that required me to put in an extension number she told me she does not know how that happened but she will put me through to the Authorization Department only for her to put me through to the automated menu again. I still do not know if I can go for the procedure on Thursday since I have not received any Authorization from Bonitas. Their service service has been very poor and I am not satisfied at all.
