So, I booked a listing with instant booking turned on and of course it went through. My host messages me a bit afterwards that she made a mistake and that she can't actually host me during those dates, so I go ahead and book another location and wait for her to cancel the reservation. She then goes on to tell me that she doesn't want to cancel because she'll be penalized and have to pay, so I should be the one to cancel. I mention that if I'M the one who cancels, then I receive a penalty in the amount of the AirBnB service fee. I sent her a cancellation request with the reason, "host requested that I cancel." She refused the cancellation request and now says that she can actually host me. I don't see any way I can resolve this in the help center or dispute center?
