Not paid

Hello Sir, I joined in a software company 16 Mar 2016. My performance was good so they raised my salary after 3 months then again after my best performance I got promoted and salary raised on October. I was happy also client and my director was happy and Company has a policy to revise salary once a year in April for all. Again that time also I got good hike into my salary. Everything was going good. Everybody was happy. But all of sudden my client started torturing me mentally expected me working in the weekends. Though there were pressures but not same as it was this time. And on May 5th in the last half on working hour. I resigned because I was frustrated on this torture. But the twist came now ! After 1-2 hours of my resign. Company blocked my official email ID without my knowledge and I was told in the middle of the night by one of my colleague that Director has changed your password and you are not suppose to come from tomorrow. I was ready to serve 30 day notice to get job in the mean time. Because I have a baby and my family has many financial dependent on me. But HR said no notice M, stop coming from tomorrow, but we will consider it as your notice period. When I asked for my salary if I will be get paid in next month they said NO, even after my insist to serve notice they said if so, then they will write bad review on my relive letter. Till now they have not given my official release and paid a single rupee. Secondly, I was taken some money from company and there are still some amount to pay from my side. So they said clear your money and collect your doc. Where I requested if I don't have job then how can I pay you. But they didnot listen anything. Please help me.. I am running in financial problem .. my 8 months son my wife my mom every body is in problem because of loosing my job.
