Manline Truck hit my car and manline company never answered me.

My car was hit by manline Truck on Friday the 30th of October 2020 on the N1 road going to Bloemfontein and the driver did not stop so we didn't get the registration number of the truck but the name written on the truck. The truck was coming from Kroonstad side heading to Bloemfontein as well. We then reported the matter with the Glen police station and received a case number. On the 4th of Nov 2020 I called the manline company and asked if their trucks have cameras and the person I spoke to said yes. After I explained what had happened the person hanged up the phone. On the 4th of Jan 2021 I send an email to the company and they never responded. Till today my car was never fixed nor my matter attended to.
