From an online site:
All of Facebook's customer service is handled online, through the Help link at the bottom right of every Facebook page. Select the help topic relevant to your problem, then click the "Send us a message" link at the bottom of that help topic page. This will flag your issue specifically to your problem.
There is a press contact phone number, (650) 543-4811, but they probably won't be very happy that you used their interview request line for customer service.
In general, most online companies don't provide a customer service number; it would be way too expensive to have the number of people on staff necessary to handle their ~50 million users. With online help, they can more easily handle issues as they come in, without having to turn you away with a busy signal or keep you on hold.

Call first then send an email telling them that if they do not close the page due to fraud that you will be contacting the police in Palo Alto and turning it over to their internet fraud division.
