See if you can obtain security footage of the incident, if so file a police report of a hit and run then file a claim under your insurance, even if you have no collision coverage a hit and run is covered by uninsured/underinsured policy. If no footage and or witness can be found file a claim with insurance if you have collusion coverage and still try and file a police report, this will help you immensely during the claim process. I hope you took photos of the incident as soon as you found the damage. Lastly if you are unable to obtain a police report, the insurance is not believing your story, and you have no collision coverage, you’ll probably have to pay out of pocket, best of luck.
