Tiffany, I understand that you are upset and I would be too. As soon as I saw that there was an issue I have contacted AirBnB directly. That's why "they (AirBnB) contacted you". I have nothing shown that you have tried "to contact me multiple times over multiple days" !!! The availability calendar is automatically sync with all the other calendars. The problem that occurred, was that approx. 3 hours before you did the instant reservation, another reservation was made into the same property. So the problem was not on my side, as I have submitted proof to Airbnb including a digital time stamp from the reservation system. Airbnb had asked me if it was ok to refund the money, because I have a strict cancellation policy, and I agreed to it. Why not! It is common sense. Even though it was not my fault, it was Airbnb's fault that there was a glitch in synchronizing the calendar. These things can happen, though they shouldn't happen. And FYI, Airbnb has NOT banned me from hosting and has NOT fined me. Airbnb actually apologized to me for their mistake. I am still hosting and my homes have all great reviews.
Please stop with these defamatory lies!!!
Again, a glitch in the system can happen to anybody, no matter how big the company is!
