Please check cancellations made during this period.
Most likely, a customer managed to book before the dates were closed, and then canceled the booking later; then, the room automatically returned to sale and became available for booking, despite the closed dates.
If there are no cancellations, please send a request to us by e-mail at firstname.lastname@example.org. In your e-mail, indicate the property ID, booking number, and dates that have been closed for sale. Our specialists will check the reasons why the booking was made and will inform you about the result.
