Airbnb deems itself as a 'Limited Payment Agent' - which means it hides behind being an intermediary between guests and hosts when collecting and releasing payments. Otherwise it would be wide open to collusion fraud risk.

If you check the above payment terms at 9.2 you should pay close attention to the clause ;
Each Providing Member understands that Airbnb Payments’ obligation to pay the Providing Member is subject to and conditional upon successful receipt of the associated payments from Purchasing Members
What this means is that as soon as you receive email notification that there is a problem with airbnb collecting payments, it's going to be your headache unless it is resolved by the guest within 24 hours.
It's too late in your case to do anything now. Don't expect airbnb to underwrite your losses and raising debt collection processes seems unfeasible and onerous.
In summary, if you receive such an email (usually for last minute instant bookings, live trip extending amendments, and long term bookings) it's time to act fast and decisively as a host if you value remuneration.
