I also have a question related to insurance.

Few days ago, I saw minor a damage on one of the doors of my car.  Looking at the damage, it appers that someone on parking lot might have hit my car while parking or pulling out of parking lot.  I did not see that and no one left any info (i guess i am too naive here).  So, my question is, could I get this fixed if I call my insurance company.  My understanding is insurance companies may not be helpful if it happened in a parking lot.  Never been to this situation before, so not sure how it works.  Any info on this is appreciated.

Thanks.
