salary issues

sir, I worked some educational institutions for 2 months. after finishing 1 month, they give 5400 check. they told don't submit check in bank. I don't hear this. I submit the check, it was bounced. they give salaries for remaining teachers. they don't give the salary only me y because the check only bounced me. after 2 weaks the check missed, I really don't know how the check was missed. I have so many time begged that institution, they simply told wait. I have the photocopy of check and evidence of call recording. can I do anything? there's any possibility to get my salary..
