Is there a duty to pay the liability insurance in the event of a flight from your UN?

Hello I drove a parking car into the car in August (I was standing in a waiting lane and sat in the car). The causer escaped, but I have his license plate and witnesses. The police also recorded the accident and have been investigating the accident for 4 months now. At the opposing car probably also a damage was found in an introduction … Now however, the opposing insurance refuses to pay, since you probably do not have any insight into the investigation files Is there any time limit or other means of pressure? Because it’s pretty bad for me who drove the other car, because it was demonstrably (announcing the opposing UN at the police) at the scene, but the opposing UN denied that it was driving itself. However, the stated driver has not yet been pre-loaded. Do I have to accept such a thing?
