Hello,
We use Airbnb often and recently had an issue. We traveled to Paris a year ago but just received a call from Airbnb support that a host was trying to recoup funds! She reported that 1 year ago she set up and paid for a taxi transfer for us and we never paid her. There was distinctive messages back and forth that we would not require her to do this for us. After sharing screenshots of the conversation with Airbnb they denied her claim.
The host are Patricia and Deborah the listing heading is Montmartre Paris 2 rooms 2/3 Pers.
