Contact Booking.com

How does a person contact Booking.com?  either by phone or email.  My credit card was just charged a small amount by "Booking.com" from a site in Amsterdam.  I need to know if this is a scam or real.  It's related to a reservation I just made. I can't find ANYWHERE how to contact them.


You can email them using the Inbox icon on Extranet.  There should be a phone number shown there as well.
