@Nebojsa10,
Are you saying that your bank made these account changes without giving you prior notification? In most countries, when a bank is acquired by another bank they need to send out communication to their customers informing them of any upcoming account changes, and it must be done with a certain amount of lead time, e.g., 30 or 60 days in advance of making the changes. Usually, the message will instruct customers to update any direct deposit or payment setups. If you were sent these types of messages from the bank about the changes, and didn't take appropriate action, you will be left to deal with Airbnb on your own. This will be an arduous affair, and will likely take a lot of time to get resolved. If you bank didn't send you any communication, and it goes against local/federal financial laws, then you can report them to the authorities to seek resolution.
