I want you to remove my balance on Apple Store so that I can change my region. Thanks.

Nobody on these boards can. Buy an item more expensive than your balance and use a different payment method to pay the excess amount; if you can't do this, ask the iTunes Store staff to zero it.

The people who answer questions on these boards are mostly other customers, not Apple employees, and don't have inside access to Apple's servers. Pick an option from those I listed above.

Nobody on these boards can except by providing ways of contacting Apple Support.
