Hi Lucky,
Airbnb don't have call centres. They usually answer us using the support messages. But I have indonesian Airbnb hosts meet up admin's email. I usually email them about meetups or seminars.
try emailing indonesia@airbnb.com
and I received these numbers from them:
"In the meantime, should you need immediate help, please reach out to any of channels below.
- For bookings, payouts and reservations, you can raise a customer service ticket to https://www.airbnb.com/help/contact_us and indicate the reservation code for reference
- For product questions, you can refer to https://www.airbnb.com/help or
Reach our Customer Service Center at +65 6622 7306 or 1800 723 1238 (toll free)."
I hope this helps
