unable to transfer funds outside the US

unable to send payment outside US except via Paypal. Airbnb has repeatedly deleted my payout method (EFT to my foreign Bank), at first it takes a few days to have it registered, then Airbnb claims payment was made, when not seeing any funds clearing on my foreign account and after inquiring, Airbnb ask me to inquire with my bank. The bank not seeing any transaction request a SWIFT MT103 (international standard serving as proof of payment), Airbnb is unable to provide such proof of payment. Airbnb then unilaterally delete my method of payment and holds the funds as a result.
