Hi @William207

This forum is for hosts and not monitored by Airbnb.

If you aren't able to take bookings, you should either have;

1. Blocked out the dates as being unavailable

2. Removed Instant Book so guests have to request dates

3. Snoozed your listing (put it on temporary hold so people can't make bookings.

Unfortunately if you want to cancel the booking, Airbnb are likely to impose penalties (see Airbnb Help Centre  - host cancellations)

You will need to get in contact with Airbnb if you want to cancel the booking. 

Contact details - see 2nd post Community Help forum.
