Something similar is happening to me. I hosted a guest and the next day after they arrived Airbnb sent the payment but it went to an account that was no longer valid so it was rejected and the funds sent back to Airbnb. I updated my payment options, selected a valid bank account and immediately let Airbnb know, both by phone and support with proof that their initial payment had been rejected.
It has been now...26 days! Yes, TWENTY-SIX days, I have sent dozens of messages to Airbnb Support, called them at least 6 times. And they keep on telling me, "don't worry, we'll check and make a new payment." So far nothing. I am desperate. The guest is leaving today after having stayed 26 days in my apartment...FOR FREE.
What can I do? When I call them on the phone I get useless customer support who are clueless and tell me this is with the Payment Center, but there is no phone to call the Payment Center, only via email and sometimes they just ignore me.
What is going on? Is Airbnb broke and keeping funds owed hosts?
