Complaint against info technology offers data entry jobs

They did froud with me. 1st she said u have no need to pay registration fee u just work for 5 days and fill 500 forms. They signed a contract in which they mentioned u have to fill 500 forms in 5 days with 90 % accuracy
I did my work with full hard work and correctly. They said they will pay 13900 salary and cut the 7100 rupees of registration fee but they pau nothing and call me that u have to pay 7100 rupees otherwise the will register a case against me.

So I wana complaint regarding them please take an action against them , so that others people can save from these types of Fraud
