I've spent 20 minutes of my time trying to file a complaint or a support ticket with AirBnB and it seems all but impossible. I left "feedback" which afterwards I was told "was not a ticket and no one will get back with you" and then got redirected here.
Sorry for venting, but if you have a link to where I can file a complaint or open a ticket that would be great. It sucks that AirBnB has decided to intentionally hide / disable communications between thenselves and their customers.
