[Skunkworks] Facebook fan page admin

Hey guys, I am at this organization where no one knows the account that was used to create its fan page. The previous admin(s) vanished with those details. Is there a quick way of getting around this? Trying to contact facebook guys is proving fruitless - unless I don't know how to... Anyone with a workaround kindly assist. Oh, and same case to twitter account... Kind Regards, Geofrey
