I booked a hotel reservation through Hotwire. I chose a hotel for a rate of $61 per night. The summary showed the $61 hotel rate when I hit the "book" button. Immediately after booking this hotel through the Hotwire website, the reservation showed a hotel rate which will be charged to my credit card, of $67.20 per night.
Called customer service, and also sent email, to complain and request a cancelation. Customer service refuses to cancel stating, "all reservations are final." I have saved screen shots showing both the rate I reserved and the rate they charged after I made the reservation.
