You said that the bumper jumped out, then most probably the paint is scratched. in this case, you need a report from police.All garages (including dealerships) dont fix the body of a car unless there is a police certificate.
I dont know which company you mean but i will suppose you mean the dealership which doesnot give waranty on damages caused to the body due to accidents.
After you take the report you can fix ur car.send me a private message in case ur need the address of a good private garage.
