Techavera Solutions - Not got salary

I joined Techavera as Business Development manager but the profile I got to know was calling. They ask employee to submit the original marksheet and later I got to know that they were just taking money from students and not giving any worth classes. They don't have any current.account to take fee and even not registered under labour law or any other legal place. Initially they told me I will get my salary on the name of company later I got to know that they will give salary via paytm. They didn't give me any legal documents from there side that I am working there. No training was given. The owner mentally harrased me every time to trap students and get them revenue later when I understood they were fooling employee and the students I decided to leave. I worked there for * days but I am not paid for my * days. Help me get my salary. They keep employee like prisoner who are not allowed to take call from home, no food no break. They checked the personal phone. I was mentally harrased
