I recently paid a wireless bill via the carrier's online bill pay process. After successfully completing the transaction, it dawned on me that I was not provided the option to disallow the site to retain my CC information. Additionally, there is no procedure available for me to remove my CC information after the fact.

I questioned the practice on the carrier's forum and was told:

"it is due to the security and write/change access to the particular program this info is stored in. . . . and the wireless industry have a very strict CPNI (Customer Proprietary Network Information) data policy monitored and enforced by the FCC."

Does this sound plausible? I'm not satisfied with that response. So I came here to get advice from the pros. What further inquiries might I pose with regard to the lack of ability to remove my CC information, where and how the info is maintained, how long, by whom and how secure it is?
