Hi @Jeremy1330 To 'jog' the search algorithms I would suggest editing a few random things on your listing, such as adding a photo or a few words to the description. Also try lowering your cancellation policy, at least temporarily. And/or adding a discount for whatever. All these things can help promote your listing in search results.
I am curious, how did you convey to this guest that you couldn't accommodate them for a couple of extra nights? I am curious why they seem to have taken great offence because of it.
