i NEEDED TO CANCEL A RESERVATION. i ACCIDENTALLY CANCELLED THE WRONG ONE. GUEST WANTS TO REBOOK BUT AIRBNB WONT LET ME UNLOCK THE CALENDAR. HOW TO UNBLOCK?
@Faith20Contact Airbnb and explain the situation. Only they can unblock the days, and I'm sure they will under the circumstances.
However, why are you trying to cancel a reservation? You will be penalized unless it's an instant book reservation and you're not comfortable. If that's the case, again, contact Airbnb and get them to do the cancellation for you.
