Aamir, the same thing happened to me. Someone stole my card and charged $1114 for a reservation. I contacted Airbnb and they said "Thank you for your reply. We understand your concerns, but please rest assured that a full and thorough investigation has been carried out on the disputed charge. As outlined in the previous message, a refund cannot be issued in cases in which we believe a friend or family member who has access to your payment method has used it unintentionally." This is lunacy!! Why is Airbnb protecting criminals over customers? They need to be held accountable. I will never do business with them again!!
I did reach out to my credit card company and they are investigating. They have credited my account, but Airbnb should still do the right thing and protect its customers.
