I have the same problem and when write them, there is an outside note that says "Please not that this information is used only to improve your FAQ content and is not sent to our customer service team".
I unlisted from Airbnb for one year, now I listed the place but Western Union is no more accepted from Airbnb. So I filled the "wire transfer" but the infos they asked me are not enough to be paid since by bank uses another bank so I need to insert more that one SWIFT ect.
I am desperate, I cannot find the way to get in contact with them!!
Thank you.
