Hello @Temba-Tsheri0,
I'm not sure what the problem is.
Your international wire showing default just means that you'll be paid by international wire.
Do you not want this now?
If you don't want it then add another payout method and make the new payout method the default one when it's accepted by Airbnb. To make a new method the default when it's accepted you click the "Options" button for the method and select the option to make it the default one.
The post below about difficulties of receiving payment by bank transfer in Nepal may be of help.
