Constant Poor service delivery

After my car was involved in a car accident November 2019, my insurer MiWay appointed Ashlee Panelshop as their preffered panelbeater. Since then I haven't received any feedback on the progress of the repairs until I went to their premises 8th January 2020 to find my car dusty and untouched. Allan, the guy who orders parts said all the parts has arrived on the 13th of December 2019 and he doesn't know why they haven't started any work on the car. The Ops manager Morgan told me he didn't know the parts had arrived and they will start the work right away and should be complete by friday the 17th of January 2020 if not they will lend me a Courtesy car to be mobile in the mean time. On the 22 January I went to their premises again due to not receiving any update on the progress of the repairs only to find out that they had just stripped the car and apparantely they didn't order door hinges and they are still waiting for them to be delivered so they can start with the repairs and don't have the estimated time of completion and don't have any Courtesy car to lend me as they promised me.
