Reservation agent blatantly lied - looked at several hotels and rooms to find a pet friendly one, kept saying they had sold out and continued to offer more and more expensive rooms. Finally took one, which he also said was non-smoking. We got to the hotel and were told we had booked a smoking room and that no pets were allowed in any rooms in the hotel, so the cat had to sleep in the car. The manager of the hotel gave us a non-smoking room instead, which we had to pay for. It was $34 cheaper, meaning the rep had made a commission or something like that. The hotel manager said we should call the reservations agent to cancel the reservation and be refunded, so that we would not be charged for two rooms, and after an hour and a half on the phone, and after they spoke to him as well, the the rep told me expressly that I would be refunded. A couple days later I got an email from the reservations company saying that they would consider giving me a refund and would get back to me in 7-10 business days, but that they probably would not because they have a no cancellation policy that I had to agree to to book the room, and they asked for any documents I had to "support my case." When they did get back to me, they decided to give me a refund, minus an unspecified cancellation fee, and said I would get it in 10-15 business days.
