I Net Solutions — data entry work - home based

Hi,
I was looking for a wfh job, and mala sharma from in net solutions contacted me saying they have a data entry wfh job for which they will be paying 190/- per page. I agreed and signed their document online, the next day i received their workload and i started working on it, after two days i searched about their company in internet and found they are doing fraudulent activity, hence i whatsapped her that i want to quit this, she immediately blocked me, then i called and mailed customer care, they said you have to pay the utility charge as mentioned in the agreement. Now, an advocate keval das pathak is calling and saying that he will file a case against me for not paying the utility charges.
Kindly help me in this regard as the company itself is a fraud
