Sorry this has happened to you. I have twice dealt with Airbnb CS about having a clearly inaccurate review removed. I'm afraid it totally depends on whom you get on the phone (and do always phone because the emails can take forever and sometimes they close the case without having resolved anything).
The first time, the Rep was really helpful, understood completely that the review did not match the correspondence with the guest (ALWAYS keep this on the Airbnb system so that you have proof) and removed both the review and the ratings.
The second time, the Rep was useless. He just said that it was the 'guest's experience' and the review didn't violate any policies. After repeatedly explaining to him that the review contained a lie, which would be obvious if he read my listing/correspondence with the guest, he said he would look into it and email me. I could tell by his tone that he had no intention of doing so and I never heard from him again.
Other hosts have said that you can get better results by contacting Airbnb on their Twitter account. I have never tried this myself, but it's worth a shot.
