I’ve often wondered what came of this. That is seriously f’ed up.
Did you call the chief of police? If not, give it a try. You certainly deserve to get better service than this.
FWIW, I’ve had the same problem up in LA with LAPD. Had the name and location of someone who was using my credit card (he worked at a hotel I had stayed at and ordered stuff to be delivered to the hotel!), but they did nothing.
