Guest called airbnb to cancel, but didn't cancel

Hi All,

We are fairly new to airbnb/hosting (since 8/2018).  Yesterday, Airbnb called me to wanting to cancel a 9 night reservation for a guest that was about 25 days away.  Our cancellation policy is moderate so I asked why they couldn't just cancel without penalty.  The CSR said that because the guest had opted to make 2 payments,  I had the option of either keeping 1/2 of the payment or I could refund all of their amount.  While I was dissapointed to lose the reservation, I felt it was the right thing to do to OK the refund.  As of this morning, the reservation is still on my calendar.  I am annoyed that the reservation is still there because we want to allow for someone else to book.

Should I ask airbnb whats going on?  Should I contact the guest?  Or am I better off waiting.  Not knowing is killing me.  I'm afraid they may wait another week and cancel.

Also, I don't remember reading anywhere about 1/2 payments from a guest being an option for guests to keep regardless of the cancellation policy.  Is this correct?

After messaging airbnb, they "forgot" to cancel the reservation.  I still don't understand the cancellation policy though.
