@DorothyAnn0 You are a Superhost with 60 reviews (in your two other properties I suppose) and accepted an inherently high-risk guest with no 'bookings or reviews' which turned out to be a 'hothead', the type most hosts are so leery off. And then (of course), you came into direct conflict with the worse side of Airbnb, who you had 'requested' a No-Refund-Policy, but didn't get? What does that mean actually?
Your responds to two most recent guests were also quite combative and may not serve you well, for they will tend to spook, rather invite, future guests, for they show an uneven temperament.
Not the end of the world, we learn by experience, if we are willing to listen.
