Today, November 17th, I received 2 emails about 2 different reservations being cancelled. The arrival dates for both room was on November 2nd. Had we known these would be cancelled, we could have removed them from our system. This happens frequently. The number 1 booking site for declined credit cards on date of arrival is Booking.com. Soon this frustration will get to me and we will begin cancelling these declined bookings regularly and lead them to speak with Booking.com.
