I declined a reservation last month and Airbnb has listed it as a cancelation

[Barbara98]

A guest asked if my place was available during a certain period. I never accepted, I messaged him asking if he could change his dates. The next day he decided to stay elsewhere.  Why is this listed now as my decline??? I want to get it changed.

There are no automatic "host cancellation" reviews on your listing.  I believe the guest has cancelled the request at their end and it shows as cancelled in your reservation list.

There is a cancellation from many months ago on your profile -  some time prior to April - are you talking about this?
