In addition to any other remedy contained in this chapter, injunctive relief shall be available to any customer aggrieved by a violation, or threatened violation, of this chapter in the same manner as such injunctive relief would be available if the financial or credit records concerning the customer accounts were in his possession. In any successful action by the customer, costs together with reasonable attorney's fees as determined by the court may be recovered.
