US EXPRESS Promised job turned into lost job Internet

I was sent out the week before last for orientation with USExpress. I was told I had the job and would get a northeast regional position home on the weekends. I would make $58 a day orientation and they would reimburse $119 of my gas money if I show receipts since I decided to drive instead of ride on a bus for 15 hours.
 I got there and of 17 of us only 3 were given trucks at 5:00 on Friday. We all had to set thru orientation and did not get paid because they said you dont get paid for anything(including gas reimbursement) unless your hired.
I have the email stating I was hired if I was sent to PA as long as a passed drug test and physical which I did. They made me sit all weekend in the hotel and Monday also ; they were finding one thing after another so I wouldnt be hired. Finally on Monday afternoon they found a job on my tax forms that I only made $400 with(so obviously didnt work there long) and I could not verify the name of the company so they sent me home.
I had to pay for food for 6 days, my gas there and didnt get paid for orientation and of course I am now jobless because I did quit my other trucking job because I was told I had the job. Not to mention when I got there I was told on Thursday of the orientation I wouldnt get the northeast regional weekends off. They thought I lived somewhere else and their map didnt go down where I lived(though I gave them my zip code and was reassured)
I actually have the email with all this info including the promised northeast regional position. What do you do though. Now Im sitting here with a 35 week pregnant wife and 6 year old daughter, 3 weeks with no check and still stunned a company could be so cruel!
