WA state Landlord-Tenant Act regarding what constitutes a detailed invoice for return of security deposit.

My former landlord is refusing to return the majority of my security deposit. I received an invoice from the company that made repairs to the apartment, but the invoice didn't specify how much money was retained from my deposit for each task or the number of labor hours and rates for the work done, just a list of the tasks and a total for parts+labor and man-hours. The repairs were minimal; however, my former landlord is charging me nearly $1,000 for the work done (things like replacing the wand for a horizontal blind and sanding spackle-filled holes). It has now been 24 days past the 14-day required timeframe for my landlord to send me the remainder of my deposit or a detailed invoice.

What, if any, legal rights do I have since my landlord is refusing to send me the invoice?
