If you wish to contact Airbnb support you can do one of the following.
Log in and click on "Help" and then type "contact airbnb" in the "Ask a question ..." box. Then click on the "I want to contact Airbnb" link.
Then click on the "Contact page" link near the end of the page.
You can also type "contact airbnb" in the "Search the community" box on these forum pages where you posted your question. Scroll down a little in the list of suggestions that appears and click on the "Contact Airbnb: A Community Help Guide[UPDATED]" one. That lists phone numbers and ways to contact them via Twitter or Facebook.
Steve.
