(C) Disclose whether interest will be paid on deposits and the applicable rate of interest.
(D) Provide the customer a receipt for any deposit within ten business days of the date that the deposit is collected.
(E) Return the deposit within seven business days if the customer cancels the contract during the rescission period.
(F) Apply the deposit to the final bill and promptly refund any excess to the customer when service is terminated.
(G) Not require an applicant to pay the balance due another retail natural gas supplier or governmental aggregator as a condition of establishing credit or providing competitive retail natural gas service.
