I recently booked a room for two nights on Booking.com. The rate in NYC was advertised on their website as $516.80 for 2 nights +14.75% tax +3.50 a day city tax. I took a screen shot of this rate on my computer at 12:55pm before I selected the "reserve it" tab on my computer. The total for 2 nights including all taxes should have been $600.03, but when I received my confirmation at 1:00pm, my billl was for $678.00! Despite my submitting this screen shot to their customer service dept., they claimed the reservation was not cancelable. I spoke to 2 different agents including a supervisor and all they did was stonewall. Finally in desperation I called the hotel directly and after learning of my situation, they agreed to cancel the reservation for me as a onetime courtesy. Don't use these crooks!
