[Resolved]  Dgs Sol — didn't receive money after work completion

I got a call from dgs sol, maharashtra where i was given online typing job. The target was 800 forms in 5 days for rs20000

I have completed my work before 7 days & submitted. I have checked the forms for typing mistake but there was no mistakes.
Then they made me wait for qc report where they had modified and made mistakes in the form and mailed me.
I was shocked to see that... Now they r demanding penalty of rs3900... Giving threats and told. Me that they will take legal action against me...
They fooled me and i didn't get a single money after doing hardwork for day and night.
