Whenever a financed insurance contract or contracts is cancelled, the insurer shall return the gross unearned premium or premiums, if any, that may be due under the insurance contract or contracts, directly to the insurance premium finance company for the account of the insured, as soon as reasonably possible, but, in no event, shall the period for the return exceed sixty (60) days after the effective date of cancellation. In the event that crediting of a return premium or premiums to the account of an insured results in a surplus over the amount due from the insured, the insurance premium finance company shall refund the excess to the insured, provided that no refund shall be required if the refund amounts to less than one dollar ($1.00).
