N.J. Stat. § 56:8-88
No telecommunications service provider or any person, firm or corporation acting as an agent or representative on behalf of a telecommunications service provider, shall, on behalf of a customer, fail to make any change in a provider of a telecommunications service for which there are multiple providers when such change order has been received in a manner that complies with federal and State rules and regulations. All such change orders shall be properly processed to assure that the order is completed and service will be provided by the new telecommunications service provider of choice within 30 business days of receipt of the compliant change order, which may be extended for good cause by the board for an additional 30-day period, unless otherwise agreed to by the customer, or as specified by rule or order of the board, or as agreed to by the telecommunications service providers involved in the change, or by federal law or rule.
