Sorry to hear that, what a pain...
I 2nd calling the Police for a report then at least it's been reported. Especially if it happens to turn up at a crime scene somewhere
Most will do it over the phone now so you can do it from home. Just try to have the numbers of the cards if possible.
Anyway here's a link with most of the information you will need for contact numbers and forms..
