Hello,
I had the same issue and was charged around USD1000. I am based in Dubai, UAE and the transaction was made on Turkish Lira currency. I blocked my card and file a dispute on my CC Company. Luckily, AirBnB acknowledged that it is a fraud and that they will reverse the transaction. Seems like this happens to a lot of people.
This is their reply.
Upon locating the transaction, we can confirm that a full refund has been processed on Nov 6, 24 and you should see a credit in the amount of ____ shortly. While the refund is processed immediately by Airbnb, your bank and/or merchant's processing time may vary and can take up to 15 business days.
We also suggest you consult your bank for help reviewing your account and making you aware of anything that could delay the refund. If you haven’t already, we suggest you work with your bank to secure your card. If you’ve already filed a dispute with your bank we kindly ask that you cancel it.
We sincerely apologize for the inconvenience this has caused. If there is ever an issue with a reservation or transaction in the future, please contact us. We’ll be happy to help!
