@Leandro268 I'm glad your issue was finally addressed satisfactorily.
So you experienced how difficult, inefficient, and unreasonable customer service can be. Part of that is that just because a customer service or "community expert" tells you something, doesn't mean it is true, unfortunately. Both hosts and guests will get told completely different things by various customer service reps.
When I first signed up to host on Airbnb, I had a question about an aspect of listing. One "community expert" told me that what I wanted to do was not possible, another told me that it was not only possible, but that it was simple to set up and explained how to do it.
That's what I meant about the host cancellation issue. CS reps will tell a guest that a host can do the cancellation without penalty, but the host then does it and gets penalized.
