Wrong job placement

I'm unemployed for about 5 month's now. Got a phone call from cozens recruitment company to let me know they found a job for me. Have to start the next day. It was a stock controlling job at Adriatic. Got there the next morning and had no idea what I must do. Stock controlling was not on the list. I packed boxes away and putting stuff on a trolley. After 2 days, I flipped out and went and talked to the, I think she is the HR manager, Beverly was her name. Cozens made a mistake sending me that job because I not a trolley boy and done stock controlling 10 to 12 years ago. Worked for 2 days, and haven't received my 2 days pay. Cozens recruitment company is the worst recruitment company ever. They don't mind were they place you, all they care about is the money they get in for placing a person in a job.
