[Resolved]  Uptask Services — legal notice against me without any reason

Hie, i took work from home from uptask services. I have completed 90% in 10 days, with rarely mistake and after days that forms automatically submitted. Then after one day they call me and tell mi your 300 forms are wrong please pay 5, 000/- rs. I said no bcoz rarely forms are wrong not that much forms they said no that showns in my computer. And they said if you not pay then we take a legal notice. Then i said i said i was complaining against you in police station. And they send me a notice without any reason what can i do?
