Section 64.1511 - Forgiveness of charges and refunds(a) Any carrier assigning a telephone number to a provider of interstate pay-per-call services or providing transmission for interstate information services provided pursuant to a presubscription or comparable arrangement or on a collect basis, and providing billing and collection for such services, shall establish procedures for the handling of subscriber complaints regarding charges for those services. A billing carrier is afforded discretion to set standards for determining when a subscriber's complaint warrants forgiveness, refund or credit of interstate pay-per-call or information services charges provided that such charges must be forgiven, refunded, or credited when a subscriber has complained about such charges and either this Commission, the Federal Trade Commission, or a court of competent jurisdiction has found or the carrier has determined, upon investigation, that the service has been offered in violation of federal law or the regulations that are either set forth in this subpart or prescribed by the Federal Trade Commission pursuant to titles II or III of the TDDRA. Carriers shall observe the record retention requirements set forth in § 42.6 of this chapter except that relevant records shall be retained by carriers beyond the requirements of part 42 of this chapter when a complaint is pending at the time the specified retention period expires.(b) Any carrier assigning a telephone number to a provider of interstate pay-per-call services but not providing billing and collection services for such services, shall, by tariff or contract, require that the provider and/or its billing and collection agents have in place procedures whereby, upon complaint, pay-per-call charges may be forgiven, refunded, or credited, provided that such charges must be forgiven, refunded, or credited when a subscriber has complained about such charges and either this Commission, the Federal Trade Commission, or a court of competent jurisdiction has found or the carrier has determined, upon investigation, that the service has been offered in violation of federal law or the regulations that are either set forth in this subpart or prescribed by the Federal Trade Commission pursuant to titles II or III of the TDDRA.58 FR 44773, Aug. 25, 1993, as amended at 59 FR 46771, Sept. 12, 1994
