Yes a bank statement from Airbnbโs bank.
This is what they sent me when I asked them how to get this information :
In order to get this information you can approach sender This could be obtained from the senderโs online bank account or the sending bank. The bank statement should include the following details[Account holder full name, Account details, Transaction history of the past 2 weeks prior to the transfer, The bank transfer to Revolut, including the name of the beneficiary and the amount and date of the payment]. Also, it could be a screenshot of such a confirmation from the senderโs online banking.
I feel really bad about it, it seems that no one from Airbnb can help me with that and all my money is locked.
