Staffmark review: I have not received my first paycheck pay day was 3 weeks ago

I've been waiting 3 weeks now and still haven't got my first pay check from Staffmark in Lebanon Tn and they just keep telling me to call back later because they don't know what's going on I've been calling them every day and every day is the same [censored]. Would never work for them again that's for sure. Then I be calling sometimes and they tell me to return them the call at a specific time and when I call them they don't answer or someone else will answer and say they don't know anything and to call back another day
