I booked a guesthouse in Japan that I thought was near the Kiso-Fukushima railway station. When I found that it was miles from the station I cancelled and booked another with a different company. Agoda did not send me any reminder that I had a booking but charged my card the full amount and then refunded part of it. I am out of pocket around AU$200. Although they didn't send any booking reminder (which I didn't expect since I had cancelled the booking) they sent me a "how was your accommodation" email.
