Hi @Melody171
Welcome to the community 😊
I am sorry to hear about your experience with the bookings refund issues.
Take a look at the link below to help you to understand more Airbnb cancelation policy,
How is the cancelation work in my reservation?

The guest needs to read and understand the reservation term and services before the payment and agreed to the policy.
Hope it help.
