(2) Disputes between a service provider and a customer shall also be subject to Sections 74 and 75. (3) Service providers shall not disconnect or otherwise change any of the telecommunications services provided to a customer, and which are the subject of a complaint or dispute, other than in accordance with the terms of service approved by the LTA pursuant to Section 55(3) or as permitted by an order made by the LTA. 54. No Unjustified Discrimination (1) Unless otherwise specifically permitted by the LTA, dominant service providers shall offer all customers the same terms and quality of service, including tariffs charged, unless different terms are objectively justified, based on differences in supply conditions, including different costs or a shortage of available facilities or resources. This prohibition shall apply as between: (a) customers of the dominant service provider who are the end users or consumers of the services; (b) customers of the dominant service provider who rely on services from the dominant service provider, in order to provide telecommunications service to other customers; and (c) customers of the dominant service provider and the dominant service provider itself. (2) Where any discrimination is shown, the dominant service provider shall be obliged to justify it to the satisfaction of the LTA, or to cease the discrimination upon receipt of an order from the LTA requiring the dominant service provider to do so. 55. Terms of Service (1) The LTA may issue an order requiring a service provider to submit draft terms of service to the LTA for approval. The order shall prescribe the schedule for preparation, approval and implementation of the terms of service. (2) Draft terms of service must be consistent with this Act, any applicable regulations, rules, and orders made by the LTA, and all licence conditions, and shall describe the basic terms of the business relationship between the service provider and its customers in the provision and use of telecommunications services. (3) The LTA shall approve all draft terms of service with or without changes, after consultation with the service provider and other interested parties, as determined by the LTA. Once approved, these terms of service will replace the customer terms then in use by a service provider and shall become binding on the service provider and its customers.
