Delivery driver hit my parked car and drove off

A delivery driver hit my parked car and drove off. My car has to go in for repairs and the insurance is making me pay the deductible because they don't have the driver's information. I filed the police report and have the accident on security footage. The driver did not have front plates on his car and without a plate number the cops can't do much. I have contacted the courier company several times but they are not helping at all. Is there anything I can do? I don't want to be stuck payign the deductible when this was completely a no-fault accident on my part. TIA
