Didn't stay at the property as the host denied our accommodation without any prior notice or valid reason

1. The property asked us to pay 50% of the charges as soon as we booked the place even though property description on Booking.com suggested that we will have to pay full amount while checking in. 2. The host denied our accommodation without any prior notice or valid reason. We had to book another accommodation at around 10 PM in the night. (Booking.com suggested some good places and helped us resolve our issue)
