Shockingly unfair and gross negligence treatment

<p>I was in an accident in November last year 2016. The car has been with a panelbeater and on the 17th of February 2017 I was asked to pay access and collect the car. After driving less than 200 meters the exhaust fell off ****erally) the radio wouldn't switch on, the back two wheels were skewed and the car had new Scratches in the front that were not there before which G&J Autobody acknowledge and admitted that they weren't there when the car was brought in. After taking the car back no one is telling me when will I have the car back. They said they needed 5 days. Yet nothing has been done on the car. And my Insurance won't give me a courtesy car. And they say the panel has no wrong doing in this.</p>
