Pje Enterprises — complaining about company asking huge money

Good afternoon sir
Respected sir/madam,

As i had got so many calls stating that calling from pje enterprises for online work, they had said that to open the mail and enter the otp in the mail, so i had enter the otp in the mail, after some time i had received a mail which includes of agreement and acceptance letter, the work said in the call and our work is totally different, hence, they said to pay the money. I sensed fraud has happened to me. Now, they have sent me the legal notices through there lawyer advocate m. Patel and advocate sagar sharma ('[protected]@gmail.com') and penalty intimation notice from lawyer advocate raj sharma and they are asking me to pay the 7900 inr which includes 4900 inr for utilities charges for company and 3000 inr for lawayer charges i have paid that much amount then they asked a another charge of rupees 13190 to close the file then sent me a noc letter then yesterday they again sent me a mail stating ur case is reopen you have to pay 11950rs, you have to pay this amount by 5 and then now they are asking for 50, 000 more or else they will file a criminal case on me. I asked them that i don't have any money as i am jobless. They did not reply anything rather said to pay the money otherwise they will file a criminal case against me.

I have not signed any agreement. They are sending fake agreement copies without my signature anywhere on it.
On my email id, they sent signed agreement (Without my signature on it) and acceptance letter (Written on their own without my signature on it) from email id of '[protected]@onlineformfilling.com'.

They are having copy of my driving license which i sent on email. Please help me they are saying to pay amount which is required. They have sent legal notice on my email.
There are many complaints against this firm online. Necessary action has to be taken against them as it is resulting in mental harassment to lot many people.
Someone please advise, i am going through mental trauma because of them. This is an open and shut case of blackmailing.
