(2) A supplier which initiates a supplier change without authorization from the customer in accordance with these rules shall issue to the customer full credit or refund the entire amount of such customer's supply charges attributable to the supplier's service for the period during which the unauthorized service was provided. In addition, any charges incurred by the customer to re-establish supply service or to change the customer's supplier after the unauthorized switch shall be refunded or credited to the customer by the unauthorized supplier. The appropriate credit or refund must be issued within a period not to exceed 60 days from the date of the initial complaint from the customer, commission, or staff.
