For purposes of a judgment awarded pursuant to an action by a consumer under chapter 19.86 RCW, the consumer shall be awarded actual damages and costs of the action together with reasonable attorney's fees as determined by the court. However, where there has been willful failure to comply with any requirement imposed under this chapter, the consumer shall be awarded actual damages, a monetary penalty of one thousand dollars, and the costs of the action together with reasonable attorneys' fees as determined by the court.
