The Airbnb number is nowhere on the site, it's incredibly difficult to find a way to email them, and they respond on twitter to save social media face but it seems they only do something to follow up if you really push.
Airbnb made over $900 Million in revenue this year with a small fraction of that going to operating expenses (which is because we as the hosts carry the majority of operating costs a hotel would otherwise have to manage - we handle the linens, the furnishings, the cleanings, the property maitenance, etc).
The least airbnb can do for the people who make them money is give them a half-way decent way to air their concerns and resolve their system issues.
I accidentally created a new listing yesterday by checking to see how much a property could earn, it took me 15 minutes before I gave up looking for a solution in their resources or a way to submit a ticket through the website (I had to go to Google to find a number to call, it's nowhere on their site!). I called, it was an easy enough solve that I can't undertand why they make hosts call in to do - if a host doesn't want a listing up, it shouldn't be darn near impossible to figure that out on their own.
