IFFCO Tokio General Insurance — claim issue

Am rameez. Am using a toyota innova car and its insured with iffcotokio. Before 1 week ago my car’s front and back bumper has been damaged in a same accident. Then that day itself i gave my car to amana toyota calicut showroom for insurance claiming and repairing., i also gave the accident photos. After two days the executive call me and said the insurance company pass only for the front portion they cant gave to the rear bumper, then i called to the surveyor (Anil - [protected]) he also said that they can’t gave to the back bumper.
I want justice for this. Its a bumper to bumper policy, so they must give the claim
