Garth, maybe your account has been compromised and your payouts are being directed to another account. This would not show up on Airbnb's end, which is why they can't give you an answer. They are simply sending payouts to the account details they have on file! If that money was being redirected that is not Airbnb's problem, I am afraid that is yours!
First thing to do is check your transaction history. If a payout has been released to you it will show initially as 'processing' and after a few days as 'paid'. If the payout has not been released to you and is being held by Airbnb for some reason, it will show as an upcoming transaction. If your payouts are all showing as paid you need to immediately contact Airbnb, show them evidence of when your last payout was received and change your password immediately.
Apart from a glitch in the Airbnb processing system in October 2018 all my payouts up until today have arrived exactly when they should have, so this payout issue is not on Airbnb's end.
The one thing we can't criticize Airbnb for is getting paid Garth, they are reliable. Check what I have said above and I am sure you will find out what has happened.
