A telecommunications carrier that enters into a contract with an operator service provider for the purpose of providing billing services for operator service providers shall include a disclosure in each customer's bill that:
(1) plainly and clearly identifies the operator service provider charges as distinct from those of the telecommunications carrier; and
(2) includes accurate information about the operator service provider so that the customer may contact the operator service provider by telephone for the purpose of contesting the charge or bringing an action against the operator service provider, or both. Upon request of the customer, the local service provider shall provide mailing address information about the operator service provider.
