Unsatisfactory care of goods

I recently received my vehicle back and the vehicle has minor damages in the interior which I have reported but to date no clear communication has been sent as to what will be done because these damages were as a result of negligence. Secondly the vehicle has not passed a roadworthy test subsequent to it being returned from repairs. Because of the accident that necessitated the vehicle being taken in for repairs, my license disk was removed and the vehicle marked as unroadworthy by the traffic department and the requirement was that a roadworthy test had to be done upon completion of the repairs. The car has failed those tests. I have reported the matter to my insurer as well as the panelbeaters but they have responded to my correspondence by requesting more picture of the damage to the interior. This is a real inconvenience for me as I have been without my vehicle for close to 4 months now.
