Airbnb Hosting Horror Stories

I had a guest ruin a rug with coffee this week. When I asked him to partially pay for the rug he responded with "You are sending me this now. It's Friday we left on Tuesday. Really." Airbnb is impossible to get in touch with. As a host, I feel we are stuck with these issues to deal with on our own. For a 25 billion dollar company, they pay pennies to help their "independent contractors" who ultimately are providing the homes for their guests. Any other horror stories from Airbnb? Hosting or Staying.
