Booking.com -- Buyer Beware! -- Totally Unacceptable!

My wife and I have reservations at a motel in Paris called Premiere Classe Roissy; it is close to the airport.  I made reservations in June after confirming our flights.  I did not notice that we would be flying to Paris leaving on September 18th but not arriving until the 19th.  So I made reservations beginning on the 18th...my error.

I contacted Booking.com three days ago.  Because of the time difference between North America and Europe, their agents were not able to get in touch with the motel staff for two days.  Finally, this morning, I received the reply from Booking.com.  This is where "Buyer Beware" comes into play:
