The driver that hit my car has ACCC insurance, and still investigating,even after their driver had taking off and after few blocks she came to stop only to said to her insurance that I was at fault, since there are not witnesses because she did not stop and police came 30 min after the fact, not to mention she didn't want to give her full information only her insurance policy no driver license nor her phone number to verify her identity, so the police had go and retrieved the rest of the information at her house, so now her insurance still investigating and I was told to use my own insurance to fix my vehicle, so far this is the worse insurance I ever had to deal with.
