Unpaid Wages

I am a Computer Developer.
I worked for a (contracting company) �employee leasing� company here in Atlanta for a total of 10 months.
For the last three months of this assignment, the �recipient company� required that we work 40 - 60 hours overtime. Yes!, for over 12 weeks, I was putting in 80 plus hours a week.
I had never been so exhausted in my life.

I was required to submit 4 different timecards a week
(3 places at the �recipient company� and one place at the �employee leasing� company).
During these 3 months, my paychecks never reflected my total hours worked,
because I was told that all 4 timecard sources were never in sync.
I submitted my time for 80+ hours every week religiously, but my paycheck for most of these weeks were less than (sometimes much less than) if I had worked a regular 40 hour week.

For four months I have been going back and forth and back and forth with the �employee leasing� company trying to get the back pay that was due me.

I have the �recipient company�s� (intranet) documentation of the total hours I worked during this three month period. Compared to the �recipient company�s� documentation, it shows a deficiency of 113.75 Hours that the a �employee leasing� company owes me in backpay.

My assignment ended over a month ago and still I am getting the run around about receiving
my back pay. The �employee leasing� company haven't even paid me the two weeks pay that was initially held back.

Could you give me some guidance?
With Profound Respect
