Shocking Turn Around Time / Lack of Accurate Communication Shocking

I was in a car accident that wasn't my fault on the 16th Nov. Discovery organised the tow truck and where my car should be delivered to. I got an SMS from the panel-beater about an hour after the car left my sight to tell me the car was there.

I have followed up on the status of my car and the assessor going to my car on, Monday 20 Nov , Wednesday 22 Nov, Friday 24 Nov and today Monday 27 Nov. Every telephone discussion I was assured that the assessor has been arranged. For example, Monday I was assured the assessor was booked for the Wednesday. Wednesday I was assured the assessor was booked for Friday. Friday still no assessor had been to my car and I asked for the managers email. I emailed the manager and I have yet to have a response on that mail. Today, the call center agent advised that no booking for an assessor has been made yet. I asked to speak to the manager and was told they needed to confirm where the car was. (they chose where the car should go 7 days prier and I received an sms confirming the car was at that panel-beater on arrival). This is also the same manager that has not come back to my email, 7 Days and counting to get a assessor to go look at my car, at a place discovery chose my car to be delivered to. What would happen if I didn't phone every second day? Where is the accurate communication? Where is the effiecient help? I do not have a courtesy car on my policy... and because Discovery takes their time to do a basic task, I have extra costs building up to get around. This is also not the first time I have had issues with their communication or their turn around time.
