Non Payment Of Salary And The Employer Is Not Ready To Take Any Phone Calls.

What are the legal steps to ensure I receive the overdue amount of salary. The employer has the habit to not pay the sums due to the employees who have left the company. He is arbitrarily making deductions and I have email as evidence. He is blatantly saying that he is keeping my payment on hold because I am not agreeing to this full and final settlement amount.
