The fax indicates if is for Expedia, HR Department. It's not from Expedia. The call back number is 877-733-4384. I suggest everyone call them and pretend that you are interested in their All-Inclusive $149/person to Cancum, Costa Rica, Bahamas, Dominican Republic, Puerta Vallarta, Cabo & more.
Now it is a "Expedia" advertisement for travel booking at 877-733-4384, but there is no removal number and when you call it is a different travel agency supposedly. When I called to ask to be removed they said you have to call the other number...
