Airbnb took $470 from our security deposit!

The host claimed that we made a damage soon after we left their condo. The damage was already there when we were there but the host claims that the maid took pictures of it before we were there and after we left. I contacted airbnb and told them can this host just lie and take money from us like this and airbnb kindly said no, but they will investigate. Few days later, airbnb took $470 from our credit card. I reached out to the supervisor and she hung up on me. She didn’t want to deal with this case. They just want us to pay for the damage we did not even make. Happy host who gets to have free $470 from an honest family stayed in their condo for one night. We went there to show our kids snow and it turned out to be a stressful, deceiving disaster! I feel so bad for airbnb. Never ever using airbnb again!
