Third party claim nightmare

A client of Discovery Insure drove into my car. So the third party claims process starts. Firstly, I need to book an assessment for damages. Discovery will arrange this. So nothing happens. I follow up, then they say that I declined an assessment, but I never had information on an assessment. I asked for proof of communication that I declined an assessment, then I never hear from the Discovery person again. I phone, but can't get hold of this person. Then I speak to the supervisor. She helped me and an assessment was booked.

Discovery use Netassess, The assessment was done, and I was supposed to get feedback within 2 working days. About three weeks later, I finally het the quote from Discovery. Incorrect. So now I have to take my car to a panel beater for another assessment. Then I hear that the original assessment was done incorrectly, since the bumper wasn't removed in order to be able to see all damages. I het a new quote. Send this off to Discovery. Nothing. I follow up, follow up, then after 3 days the Netassess company doesn't want to accept the quote. There is not supporting evidence like photos. I received no assistance in this from Discovery, they simply forwarded the new quote to Netassess, they did not inform me to either obtain photos or book a re-assessment.

All the while I am paying for a rental car while the assessors, panel beaters and Discovery sit back and take their sweet time.

So then I start to deal with Netassess - Discovery's choice of an assessment company, but then I run into more trouble, since the person at Netassess tells me that he will phone the panel beater and sort out everything. Then I phone the panel beater who says that Netassess didn't phone, I phone Netassess who says they did phone. Who should I believe? And where is Discovery in all of this?

Day 5 of paying for a rental car while my car is sitting stripped in a panel beater shop. Discovery has not sorted this out for me, I have no idea when something will happen. The process is completely invisible, I have no idea when to do what. Or how the process should work.
