My car was hit by a car at the back On the 29/8 while waiting at a junction. My bumper needs to be replaced and his car had his bonnet dented. The person and I immediately went to the police station  to make a police report. While waiting to make police report, he told the police that he will come back later As he had to do something.
I have waited and made my police report. Also submitted my claim to Honda with the Honda Insurance. Claim all approved and car should be ready next week.

However I was just told by Honda workshop that the person did not make a police report. So according to him the investigation is not complete until he makes a report.

I understand that if he don’t make a police report, I cannot claim his insurance and I will lose the NCB. I’ve had checked and his car has a valid insurance.

I have Dashcam evidence and also the photo of his car.

What are my options now?
