Hi @Robbi0 This is a very sneaky trick that Airbnb is playing on hosts. It is now asking guests that want to cancel to get the HOST to cancel! I recently saw this. Something like "Tanya would like you to cancel the booking". NO WAY IN HELL. Tanya can cancel if she wants, but why would I cancel for her? I saw this and called Airbnb support to complain. This is a very tricky way to get the naive or inexperienced host to cancel because it's being presented very innocently - but the reality is that a host cancelling a booking has very serious repercussions.
I would suggest that you call Airbnb support, complain about the way this cancellation was requested and handled, and yell a bit. If you don't get the dates opened up, call again in another day and try with another agent.
This is a very bad way to do business, and I'm sorry that you got tricked!
