My husband and I booked our home stay at Channa's Angkor Homestay 6 months in advance. Three days prior to our arrival, having confirmed our arrival date the week before, we received an email that our reservation could not be honored because they had double booked. We were very upset and disappointed. This was a big problem as it was December 23 and all the hotels and hostels were booked for the holidays.
The only bright spot was that our deposit,which was the entire cost of our stay, (prepaid 6 months in advance) was returned.
I suggest that this was very objectionable business practice.
