Nobody at Airbnb will contact me

 @Ray92. When a host cancels a confirmed reservation, whether by accident or not, Airbnb will automatically block the dates of the cancelled reservation.  Looks like the automated review about the cancellation was not posted on your listing, but likely the blocked dates will remain. 

You should see this link to see all the penalties Airbnb imposes for cancelling a reservation:

You can try to contact Airbnb again, but with all the hurricanes, earthquakes, etc. going on, the support staff will prioritize more urgent requests for support.  

Just be careful not to cancel any more reservations!
