Poor Repair work / Extra Damages

Had a accident a while back where a brick hit the underside of my vehicle that damaged some panels and the sump so the car was running out of oil and this all happened on a highway in peak hour traffic...

The vehicle was then send by my insurer whom are PMD to Renew-It Sandton and already I can rate their service as absolute ****.

Struggling to get hold of staff / agents to assist and even explaining multiple times that the motor and turbo needs to be inspected they just ignore and proceed to fix visual damages.

Just over a month with Renew-It Sandton I get a call stating my vehicle is ready for collection, upon arrival I immediately saw that my Bonnet guard has been broken, then battery was completely dead(which they did not want to replace at first) and the bonnet did not open...

After a mechanic fixed the clamp of the bonnet they proceeded to use a battery pack to start the car(their words were they struggled multiple times to start the car, so I don't even know if damages occurred to the starter motor), they pulled the car in front of the building and let it idle so that I could further inspect their "repair work".

On expecting further I noticed that my water warning light was on and I immediately switched off the car to inspect under the bonnet just to realize that there was no water in my water tank(engine coolant) so again don't know if any other damages to the motor has occurred.

The two front fenders where the headlights sit in are also damaged / dented when they removed the headlights the first time.... and also the car was not even washed properly as it still had old oil stains from the day of the accident and also to mention, no inspection was done on the motor / turbo for any damages.

I left the vehicle there after a very heated argument and awaiting their call back...
