Unprofessional, inconsiderate and horrible service

I am very frustrated with this panelbeater, my car was involved in an accident on 02/12/21. I was then informed that they will be working on skeleton staff due to the festive season and parts to fix my car were ordered. On the 3rd of January 2022 I received a call in the morning from a lady by the name of Harriet that my car will be fixed by the end of the week. I had a courtesy car which I had to return back to Avis Rental since my plan was only for a month. On the 12th of January i called the panelbeaters again to check on the progress and was informed that they will call me back. I am very furious since every week i am informed that by the end of the week my car will be fixed. To date it is still in the painting department and l don't even trust them anymore. This is very unprofessional and very inconsiderate of the panelbeaters.
