Never leave your credit card saved on the Airbnb app or website. My card was fraudulently charged for over $200 but promptly credited back, as shown on my statement. I did not even log in to the website or app for more than eight months. I lost out on more than $10 due to currency exchange differences. Airbnb refused to credit me back, and refused to say why my card was charged without authorization. It took them more than two weeks to even reply to me. My bank can’t do anything because Airbnb returned the amount they scammed from me. My big question is how can Airbnb charge a credit card without approval or authorization? This amounts to a scam and should be considered criminal. I thought my case was isolated, but a quick search on Google turned up similar stories.
