First time trying to use this service. Was told there was only 3 rooms left so I was trying to hurry. Had to enter my email for Facebook to get the lowest rate. Then enter all of my information to book the room. Submitted. Came back to the initial screen showing the hotel and its rate. No confirmation page. So I waited for my confirmation email for 15 min. Never got it. I went back into booking.com. No record of me booking. No error came up when I submitted the booking of the room. So, I went back to the hotel to book the room again, and it's sold out. I called customer service and they said that happens sometimes and to find another hotel. What a waste of time.
