@Diah-Puji0 If you have a confirmed reservation, you will have gotten that confirmation from Airbnb. Did you book this through the official Airbnb site? I hope so- if you found the ad elsewhere, you could have been scammed.
If it was a real Airbnb booking, and your host isn't answering your messages, you can contact Airbnb and ask them to try to contact the host and get them to reply to you.
