This has happened my car twice in the past 18 month, first i came out of work and noticed my rear bumper was damaged , scrapes etc ..was so pissed off. Then last week came out of college into the carpark and noticed 2 dents in my left quarter panel like a door was slammed into it real hard. Im doing my nut over this now almost paranoid someone is out to get me LOL. Well done for reporting that ho , i wish someone had done the same for mine!
