WA state debt collection law, procedure for collecting pay from employer work work completed, unjust enrichment

How do I collect my pay for work I already did.: :I was employed through a temp service to work the senior PGA Boeing Classic at Snoqualamie Ridge Golf Course. The event service that hired me was Eventaces out of New York. I was told I would receive $10.00 per hour and my hours would be August 22, 23, & 24, 2008 from 9:30 AM -7:00PM. I worked Fri the 22nd from 9:30-6:30, Sat the 23rd from 10AM-7PM, and the finale day Sun the 24 from 9:00AM-6:30PM. My total hoirs were 27@$10.00 per hour. We were told that we would receive our pay check 7 days from the event. I received a partial check Sept 11, 2008, and am still waiting for a day that they didn't pay me for. I've called a least 5 or 6 times each week, and have been told that they sent me out the remainder of my money, but as of this date Sept 23,2008, I still have not received my pay check. What can I do to get the money that is due me? - Is this your question? Add additional information
