[Resolved]  Pro Sol — charging us on the basis of fake agreement

Hello
I am complaining about a company named pro sol. One day they sent me a mail regarding data entry work, i am a struggling student and currently finding a job so that time i needed a job. But i was confused about should i take this or not?. But that time i opened that link which was given in that mail and then an employee named kalyani (With phone number [protected]) called me and said that you just have to do the work and don't have to give any money, she also told me that after successful completion of work they will deduct maintenance charges from the salary and will give rest of the money. I said yes to kalyani and then she asked me to send scanned copy of my aadhar card so i send the aadhar card's scanned copy. After sometime she send me a agreement which is already signed with my name (I think they did the signature by themselves) also in agreement year is mentioned as 2018. And then i started the work, after 2 days i have encountered a problem with my laptop, so i tried to call kalyani because she was my contact person but she didn't respond and didn't pick my calls. So i send a mail to helpline regarding unable to do the work but they said that if you want to cancel then you have to give maintenance charge, so i arranged a laptop from a friend and completed the work within given time. But after a day they send me a mail regarding failure of qc (Quality check) report and again they send me a mail in which they are demanding maintenance charge, that time i didn't responded. After a day or two, they send me a notice (Which is marked as legal) and also they called me and abused on call that they will drag me in court if i don't pay the charge. Their advocate (I think he is fake) mailed me a notice and now they are charging us more money and continue sending me threatening mails. I am just a student and and i don't want any trouble when i did nothing wrong. I am scared by their notices and calls. I don't know what to do. Please help me and solve my problem.
