I had left freight systems to work for us express. they sent me through orientation, I did not need a physical since mine was still valid. well they left me sitting for 2 weeks then freight systems asked me to come back and they would pay for all expenses so I did. well anyway, us express charged me 100.00 for a physical. i told them i did not take a physical. i did not pay them. now they put it in with a collection agency. what is my recourse.
