No utility shall use any credit reports other than those reflecting the purchase of utility services to determine the adequacy of a customer's credit history without the permission in writing of a customer. Any credit history so used shall be mailed to the customer in order to provide the customer an opportunity to review the data. Refusal of a customer to permit use of a credit rating or credit service other than that of a utility shall not affect the determination of the utility as to that customer's credit history.
