Hi i want to change my iTunes from US to rusia and i want to reset my balance

Hello ~If you are trying to zero your balance before changing regions…you may purchase an item from the App Store for more than your balance and the remainder will be billed to your credit card on file thus zeroing your balance . You may also go to upper right hand corner and click on Get Support and they can zero it for you or:

Contact Apple for support and service

Also if you are changing regions take a look through this article as well:

Change your Apple ID country or region - Apple Support

For future reference ii is not helpful to mark your own posts as solved or helpful. It in fact reduces the chance someone will respond and try and help you.
