My car was hit and damaged by a barricade that fell against it whilst I was exiting the car park.  The wind blew it against my car and it was scratched on several panels causing $1,100 damage. There were several barricades and most had sandbags to hold them as it was very windy.  The barricade that fell against my car didn't have a sandbag.  The insurance company for the shopping centre is denying liability on behalf of their client. 
What course of action can I take against them?
