What if the foreman owes me wages and materials for migrant workers?

First, you ask your friends who work with you to call the police. Second, you look for the receipt of your material fee and get it. Third, send a text message to the contractor, saying to give him a chance to pay back the money, or see you in court. Fourth, of course, looking for a lawyer. Wait for the police to find someone to sue. Some policemen work for money.
