Hi Missangelpam,
Thanks for contacting Apple Support Communities. I understand your concern with your iTunes charges. It sounds to me like you are purchasing iTunes Gift Cards to use as your primary payment method for iTunes purchases, but your credit card is still being charged from iTunes. This article outlines how to report a problem with the purchases that were made, including charges.

I understand that you want to remove your credit card from iTunes as well. There is a process for this as well and it is outlined in this article.

If you need help changing your payment information, contact iTunes Store support. Or you may find the answer to your question below:
- If you change your payment method, make sure your account information matches the credit card information on file with your financial institution.
- If you use an AOL screen name to sign in to the iTunes Store, editing your information on the Account Information page won't update your AOL account. If you need to update your AOL account information, contact AOL.
- If your previous payment wasn't accepted, you may need to change your payment information.
Cheers,
-Joe
