How to get an authorization number?

I have tried calling the Helpdesk number 4 times. The first time, the call cut off after I went through all the typing and selecting and waiting for a consultant. The second time time the same thing happened. The third time, after 5 minutes it then asked me to leave a voice message as the person I was trying to contact was busy, THEN, a message played that said that the voicemail box was full. The forth time, I eventually got through to an agent. I know this because I could hear them fiddling with their headset ... AND then they hung up. While I have been trying to communicate with your FB team via messenger, and I have been asking them for an alternate way to get an authorization number other than calling the Helpdesk, as it takes long and it can be problematic. I have been told about a virtual consultation with a doctor, but still no other way to get an authorization number. When getting to the authorization number section on the IVR system, we are told that if it is an emergency to just go to hospital. If the procedure is happening within the next 48 hours to hold on the line. If it is not within the next 48 hours, to call back when it is within 48 hours. Given the experiences I have had with trying to get through to the Helpdesk, this is not a chance I want to take. I have tried your WhatsApp line, but sadly that only has automated responses, all of which direct me back to calling the Helpdesk. I do not need a consultation. I do not need to check my benefits. I do not need to apply for chronic condition authorization. I need a way to get an authorization number other than calling the Helpdesk, as I am unable to get through to a consultant that will answer my call and take the relevant information I need to give them before they give me an authorization number.
