Really sorry to hear that you haven’t got your domain back. I honestly thought your registrar would have it sorted out the next day.
Then again when I got my house robbed and all my stuff stolen including my car, the thief logged on to one of my affiliate programs with my computer but the program refused to provide me with the ip address.
The best defense I’ve found for laptop thieves is LoJack for Laptops. If it gets stolen they can track it down. If it gets stolen with everything else in your house you get the thief and most of your stuff. I think I pay $29 a year for the service.
