Almost two months ago a co-worker of mine was leaving work for the day and backed into the side of my parked car. She realized her error and left a note with her name and number (I work for a large company and have never met her before).
I contacted her and we agreed that I'd get an estimate for how much the damage would cost to repair, and then I'd send the estimate to her. About a week later, I got the estimate (~$1150) and sent it to her via a text message and waited for her response. After a few days I hadn't heard anything, so I sent another text asking for a response. Another week went by and I hadn't heard anything, so I scanned the estimate and emailed it to her and asked for a response. Nothing. A few weeks later I sent another reminder email, but didn't hear anything from her.
What should I do next? She never gave me her insurance information, so I can't contact them. I want to involve HR next, but I don't know what they can/can't do. I thought about finding her desk at work and confronting her there (in a polite way, of course), but I don't know if that's wise or not. Any advice will be appreciated.
Update: Persistence paid off. She finally responded to my efforts to contact her. Turns out she was driving uninsured at the time, and her insurance denied the claim. My threats to take her to court eventually provided enough leverage to get her to agree to a monthly payment model. I made sure to explicitly define the terms of the payments (dates of payment, method of payment, amount, etc.). Took almost seven months, but the incident is finally resolved.
