Help - Insurance Woes

[AWD Chaser]

Hey guys - need some advice re an insurance claim with AAMI:

I got my HSV (a few weeks ago) on a Sunday, and on the Wednesday I got hit from behind in a 3 car prang (I wasn't at fault). Police came out cause the woman at the back had pelvic pains and she was heavily pregnant so she was taken to hospital.

Anyway, I got hit from behind and pushed over a median strip which scratched up my rims (VE GTS rims), and also sustained a damaged rear bar.

The insurance assesor came out today and said no worries on the rear bar (getting replaced) but a no on the rims - his reason why is that the car wouldnt have sustained a big enough shunt to push me over the kerb and that I have done the damage by parking against the kerb - he went so far to point out that I even had brake dust in the scratches - thats when I got really p***ed off and said - mate, its been over two weeks since the accident - of course there is going to be brake dust.

I also stated that when I took out my insurance policy, it was marked as "No unrepaired damage" - it is an offence to provide false or misleading information is it not?!?!

I explained to him exactly how the accident occured, but he said - well I'll take some pictures but its more then likely going to be a no.

Now he stated that the driver at fault is with a different insurance company so its not like AAMI is having to pay out if they are recouping the cost...

The assesor also said I can now book the car in to get the rear bar fixed - do I go ahead and do that or wait till (if) everything can get done at once?

What do I do? I thought my insurance company is there to help me (I realise my mistake in thinking that now)...
