Re: You get what you order
Take pictures, preferably with a cellphone so that they photos are internally-documented with date/time and location (GPS here in the US). Always file a report with your insurance company, using these photos. Save a record of filing the report.
I had the misfortune of being in a low-speed traffic backup "merge" collision wherein my vehicle and the vehicle to the left of me came into contact (by only the other vehicle's passenger side mirror's plastic housing barely touching (and marking) the paint on the driver's side door of mine).
I took pictures, including a first one of a middle-aged woman emerging from the passenger side of the other vehicle while the driver still her her foot on the brake. I thoroughly documented the lack of damage to either vehicle pictorially despite this woman's screaming at me and her fevered attempt to stop me from taking photos (at first). She eventually calmed down and we exchanged information, despite the young woman actually driving never emerging from the car. After leaving then scene, I thoroughly documented the accident (pictures, location diagram completed using GPS info on pictures) but was unable to file immediately due to a problem on my insurance company's website.
Several days later I was contacted by my insurance company (which was also her insurance company) with a request for information about the accident, initiated in response to her filing her claim. She stated that I had admitted fault (no, no, never did I). During the conversation the insurance company referred to her as the driver, which I said was not true. They asked if I could prove it. After explaining why I hadn't filed yet (their website had malfunctioned and I didn't have Internet service at my house) I told them I would send them my already completed report, which I did. I pointed out my first picture showing her emerging from the passenger side while the driver obviously had a foot still on the brake (brake lights lit, including third high-mount light). After a couple of days they called and told me it was the best documented report they had ever received, but they wanted to know whether I was making a claim? I said no, the only contact was the mirror housing and my door, which left a colored streak on my paint that I simply rubbed off, so no need. They thanked me profusely and ended the call.
I don't know what the other person was up to, claiming to be the driver, or what damage she reported to her vehicle, but it was all short-circuited by my photos with date, time, and location.
