Why my application must to pay ?but the apps is free..have a problem in payment and shipping..I already delete the account payment but still cannot ..

Apple appears to require you enter a valid payment method as a means of verifying you are a resident of the country for which you are trying to use the store and therefore eligible to own the app, even if it is free.

See this explanation. If you can't choose None when you edit your Apple ID payment information - Apple Support

Hi

Before you can download anything from the apps store you must have a payment method.

Or you can buy an iTunes gift card redeem at the bottom of main iTunes page.
