[Resolved]  Uni Services — online fraud

I have got a call for online work from UNI services they sent e-mails one by one and called to sign the agreement and assured that they won't charge anything if we cannot do the work, but I have completed some of the work and one day they called me and said that I had to pay 8500 as penalty by that day evening 4:30, if not I have to attend the court in delhi along with my lawyer, as I was a student, i have feared about that and I have payed him the amount he asked, i have also got the Noc by email, but they have again sent the message today again i have to face the legal consequences if the penalty is not paid. Please resolve, what I have to do, even i have paid, i am getting haunted, please resolve
