I was involved in an accident with an Enterprise vehicle but I wasn't at fault. The Enterprise driver was. I called Enterprise and they are not very helpful. They keep telling me to call the Damage Recovery Unit and they told me to call the branch where the vehicle was rented at. The branch wouldn't even help me. I got a police report from the accident as well and got my insurance to involve. The insurance contacted them but no one is answering the insurance calls after they left a message. What should I do next?
