D. Revocation of Authorization

(1) By subscriber: Subscribers may revoke authorization to allow non-communications charges on their bills at any time without charge. They may do so by notifying their billing telephone company, by telephone, in writing, or via the Internet, that they no longer wish to allow non-communications charges on their telephone bill. Revocation shall be effective the same day the billing telephone company receives a subscriber's revocation instructions. The billing telephone company must confirm the revocation in writing on the subscriber's next bill. This written confirmation shall indicate the effective date and time of the revocation. Billing telephone companies must allow subscribers to revoke authorization by telephone 7 days a week, 24 hours a day.

[Comment: As with credit cards, immediate revocation of authorization is necessary to protect subscribers in the event of theft or attempted fraudulent use of the subscriber's account.]

(2) By billing telephone company: A billing telephone company may suspend a subscriber's authorization to bill for non-communications charges without prior notice if the company has reason to suspect fraudulent or unauthorized use of the subscriber's account. The billing telephone company shall give prompt notice to the subscriber of such action. In all other cases, a billing telephone company must provide reasonable notice before suspending or revoking the subscriber's authorization. Billing telephone companies must inform subscribers of their revocation policies when soliciting subscribers' authorization and when responding to subscribers' requests for information about the service.
