Dear Martin,
Thank you for contacting iTunes Store Customer Support regarding the issue with de-authorization. I can certainly understand how eager you are to get this resolved. I will do my best to assist you.
Apple takes the security of your iTunes Store account very seriously. The first time you attempt to make an iTunes Store purchase from a computer or mobile device, you will be required to verify your payment information and re-enter your CVV code. This is a safeguard designed to protect your account against unauthorized purchases.
If you are concerned about the security of your account, I recommend this article:
iTunes Store: Best practices for protecting the security of your account
http://support.apple.com/kb/HT4156Martin, in order to reset the account you need to add and remove your credit card from your account on every device you use to make purchases from. You can change your iTunes Store billing information at any time. When you update your credit card number or billing address through the iTunes Store, any equivalent information you might use with MobileMe, iPhoto, Aperture, or the Apple Store online is also updated.
To update your billing address or credit card number, follow these steps:
1) Make sure you're using the latest version of iTunes. It can be downloaded free of charge from the Apple website at:
http://www.apple.com/itunes/download2) Click this link:
http://phobos.apple.com/accountSummaryiTunes will automatically launch and the sign-in dialog will appear.
3) If you are not already signed in, you will need to enter your iTunes Store account name and password and then click the Account Info button.
4) On your Apple Account Information page, click Edit Payment Information.
Make the necessary changes. Your billing address should be exactly the same as the address on your credit card statement. This is important, because even differences in punctuation, abbreviation, and capitalization can cause payment errors that might prevent you from using the iTunes Store.
5) When all of the information is up to date, click Done.
Martin, when you update your billing information, the iTunes Store places an authorization hold on your credit card to verify your account information. You might see this authorization request on your online statement. This is not an actual charge; it is simply a test to confirm that your credit card account is active and has credit available to accommodate transactions.
Authorization requests are automatically removed from your account by your financial institution. The amount of time it takes to remove authorization requests varies by financial institution. If you have any questions about the way your financial institution handles authorization requests, please contact their customer-service department.
I hope this information helps. If you have any other questions regarding this issue, please feel free to contact me again. Thank you for choosing iTunes. Have a great day!
Sincerely,
Buddy
