Select Staffing

Friday morning, I was instructed by a Select Staffing employee to come in the following Monday morning at 8AM for orientation. I traveled 30 miles, arrived early & waited outside with several other individuals watching the staffing employees enter the building. Shortly after 8am the doors opened & they told us "Sorry, come back tomorrow." I am already unemployed. I can't afford to travel back & forth. How can they tell people to arrive at a certain time and date just to turn everyone away.
