Keep riding them Tas.
They're cnuts and they get away with this **** because people either dont see, or dont care about the level of work that is done to their car by repair shops trying to do the job on the smallest price possible.
I've had 4 crashes, 3 not at fault, all were repairable.
It took 4 months of constant shitfighting to get them to sort out the problems they'd caused. From scratching up the rear quarters to refitting a trim with ripples in it because they said it was no longer available (i walked nextdoor to spare parts and got the printout that there were 170 in Dandenong) supplied the evidence to the insurer before it went back in to fix. 2 weeks later, they tried pulling the same **** again saying it wasnt available....they almost gout the piece of paper rammed down their throat for that one.
Moral of the story - Insurance companies are cnuts and screw repairers out of enough money to decently fix your car. Therefore the repairer passes the butt-rapage on to you in the guise of a **** quality repair.
