Fuck... Get an old car and ram her car at home. OOOPPPPS! I have no insurance! Bitch...
Make sure that it not usable too..
I had that happen to me as well. I just let that fucker go... I did that to some one else as well. I just called it even in the karma department...
Seriously report it and take him or her to court. You will win but not a guarantee that you will get your cash. Especially if its a nobody... But make him or her fucken waste time and shit.....
