1) Tell the cops to write the report, and you are going to file charges for a hit and run. Its their duty, and they will try to convince you to not file charges because it means more paperwork for them.
2) Get a free call recording app, and call the place of business and ask to speak to the manager about something concerning his business. Be tactful/extremely vague until you can talk to the manager. Ask him if any of his employees drive a car matching the description and then tell him one of his employees was involved in a hit and run and you are the victim of the crime. (just make sure it wasn't the boss that did it

Ask him about the employee, see if you can get him to tell you any more information about the employee (e.g. did he work that day, is he missing the front license plate, what damage can you see).
3) After you feel you have collected enough information, call the police station back and tell them you have been a victim of a crime and reference your case number (see item #1) and you have information about the criminal. If you give them enough evidence, they can detain him and question him for hit and run. They can get the individual to give up information regarding his vehicle (drivers license, insurance etc).
4) Once you get the guy's info from police (if you can-which I am not sure of) you then either by yourself, or through the police, contact his insurance and file a claim for damages and begin the process of having them fix your car, no matter how small the damage.
5) You have rights and you can prosecute this individual to the fullest extent of the law. Make sure you tell his insurance that you are experiencing a lot of emotional distress and anguish from the accident so they can document that not only did he damage your car, but you can have a case to sue him if you wish. Worst case scenario, if the individual is convicted of a crime (hit and run) the prosecutor will look at the amount of effort/anguish you went through and the willfull disregard the person has.
Or just really look at it and if the damage isnt bad, and your vehicle looks like crap anyway, just go through his insurance and get them to cut you a check.
These are some of your options. These are your rights as a victim.
Whatever you do, don't let anyone jack you around and stand up for yourself.
