iTunes Store
What do you have to do if you have 10 cent on your iTunes Store and you want 0 cent
and you don’t hav a credit card
Give it to Apple:
"If you still can't change your country or region, or you have less store credit than the cost of a single item, contact Apple Support." Apple will remove the balance and keep it.

If you do not see your country, see if there is an "other" listing for that region. If you don't see an option that handles your issue then keep experimenting with selections until you reach one that gets you a chat session or a telephone call and get the representative to redirect you.
