To change French account
I have a French account and I will return to my country(Brazil) But I can't change my country account because there is still balance in my French account. I want to allow Apple to reset my French account.
iPad Pro, iOS 9.3.2
See the following from If you can’t change your iTunes Store country or region - Apple Support
You must spend your balance before you can change stores.
If your store credit is less than the cost of a single item on the iTunes Store, App Store, or iBooks Store, you can add a credit card to your account. When you buy an item, you will use the remaining store credit and charge the remainder of the purchase to your credit card.
If you don't have a credit card, contact iTunes Store support.
