Hotel Las Américas Golden Tower Panamá had a special Black Friday offer in booking.com. They confirmed booking, but the next day they changed their mind and tried to get 6 times higher price. The hotel is drawing in customers with scam prices and then renegotiating prices. Very unprofessional and lamentable to accept such behaviour from the hotel and booking.com as they both pretend to be top class. You can't trust booking.com to follow their own terms and keep their commitments, or the hotel to honour the price and their booking confirmation.
