As there is a billing problem with a previous purchase, follow the instructions here:
- Pay an unpaid balance in the iTunes Store - Apple Support
- Get help with an item purchased from the App Store, iTunes Store, or iBooks Store - Apple Support
- Change or remove your Apple ID payment information - Apple Support
- Payment methods that you can use in the iTunes Store, App Store, and iBooks Store - Apple Support
If you then still need help, then contact iTunes Support:
(I'm afraid that no-one here can look into your billing issue to assist you directly. This is a user-based technical support community - you are not talking to Apple here).
