File a police report with your local police department.
Keep good records and retain them. (Problems can arise later.)
Write down the names of people you speak with (police officers,
credit card representatives, financial institution representatives,
etc.). Follow-up your telephone calls with a summary of your conversation
and send it certified mail to the contact persons with whom you spoke.
Keep originals (documentation, police reports, etc.). Provide only
copies to authorities who may request them.
