Has anyone had this issue before? I have had zero contact with the guest other than the usual quick back and forth about check-in instructions. No issues, no cancellation.
You'd better get on the horn to AirBnb and ask them to please find any evidence of any cancellation. Or confrontational dialogue. Or anything prompting this.
They'll likely ignore you, but just keep at them. Call, write, explain. Lather, rinse, repeat. Be rational, just the facts, and don't get angry. And don't give up.
Yeah, when I contact support, they just transfer me to someone supposedly at a higher level, and that person responds (hours later) with some cut and paste response having nothing to do with my question and immediately closes the case.
