SweepStars are required to take the day off when they are unable to make a booking and should not be contacting you directly to advise this - we apologise for any inconvenience and frustration caused. When they take the day off, our system will then assign another SweepStar who is available.
Was this booking with your preferred SweepStar? You could always skip or reschedule this booking. You can read more about rescheduling here: https://goo.gl/QEsRq7.
