Esentire Network — Blackmailing through fake advocate and charging money.

I am a student of 1st-year BTECH and I was looking for a part-time job so that I can manage my pocket money, so I applied for some data entry job in quicker. The next day I got a whats app from essentire networks for form filling job. they give me 520 forms which I have to complete in 6 days. First I took the work but I was not able to complete the work within 6 days. Now I am asking them to give me some more time I will complete the work. But now they are charging money from me and blackmailing me for legal actions that I didn't follow their agreement. I got an email from an advocate who doesn't know fake or not. Now the advocate told me to pay 7100 to him and he will close my matter. But I know that if I will pay him right now he will charge me more money later. And I am just a student that doesn't have that much money to pay. And he is blackmailing me that he will take legal proceedings against me. I am so worried please help me.
