The monthly subscription amount is calculated, but the application does not work

Hi bandr258,

Thank you for contacting Apple Support Communities. Based on what you stated, it seems like a purchase could not be completed. You may need to change the payment method used, and contact Apple directly if necessary.

Change, add, or remove Apple ID payment methods

If your payment method is declined in the App Store or iTunes Store

Please don't hesitate to let us know if the steps resolved your issue or if you need additional assistance.

Cheers.
