College not paying the salary

Hello Sir/Madam. I worked with a private technical college in Jabalpur (M.P.) and working from 4.5 Years for the same college. I didn't get my salary over there of 22 moths, I keep on asking for salary and they use to tell will credit today/tomorrow and this type of promises they give every month. From the last 1.5 years they have not provide me the salary instead of that Whenever i asked them for salary they pay me the some/part amount of salary and they use to tell the salary will credited soon. Now from the August 2016 it has been 22 months completed they not provide me the regular salary except the small amount of salary. Now I am not working with that company from Feb 2018 and the amount of my salary is increased in Lakhs. Still they promised me for paying the remaining salary but unfortunately the management behavior is same. After lot of struggle they transferred me again a small amount of my salary last month. With me there are around 8 employee who are facing and many faculties left the college because of the same problem . could you please advise what to do now to get my hard earned money?
