Optibase - Fraud Company asking for a Registration Amount

*.I entered my personal details on Quickr regarding Work From Home jobs.
*. I get a call from a company named OPTIBASE. **/**/****. They tell me that I will have to fill *** forms in * days for which they will pay Rs**.* per form. They right away ask for my personal details like my Email id and the picture of my Identity Proof. They make an account for me right after few seconds and ask me to login to that account with only one device.
*. I ask what is the guarantee of receiving money from their end to which they sent me a contract. According to that legal contract, I will be paid the amount only if the amount of correct forms are above ***. Rs **** will be deducted from what I earn as the Registration Amount. And it also said that if the maximum limit of accuracy of forms(***) is not reached, I will have to pay the Registration amount from my own side to the company.
*.Since the contract was already made by them and it had all my personal details, I got a bit suspicious and nervous as I did want to fall for any fraud. I called the person who contacted me from the company(her contact details- **********) and asked her that why was I being asked to pay an amount if Iam unable to complete on time or if the forms are wrong. She told me "Dont worry maam, if you're unable to complete and want to just leave you can tell me anyday, You wont be charged anything"
*.I knew I could complete those forms if I try hard and maybe I'll get some money if this place is trustworthy. I had nothing to lose. So i started the work. With all my effort, sitting infront of the laptop day-and-night, checking each and every form thrice before submitting, I somehow completed the target within the time in * days. I was pretty happy since I was sure there were definitely no mistakes since i took my sisters help for cross-checking each form before submitting and correcting any mistake.
*. After submitting. I see my report which says I have failed the task and *** forms are incorrect. I somehow had a feeling that this company was fake but seeing that made me feel devastated. It was completely IMPOSSIBLE that *** forms out of *** could go wrong. I saw the mistakes in the incorrect forms shown in that report. I am a skilled typist and there was no way I could make such big mistakes in my typing. It was definitely a fraud. I felt like I wasted my * days and was disappointed.
*.Next day(**/**/****) I call on the helpline number provided by the company(**********) and tell them that I have been scammed by them and I asked them to show me the correct report since I can never believe I had made *** forms wrong. I told them that I want my money and I will like to talk to the Head officer. The woman on call kept on saying we have ** employees who are being paid and the server cannot be wrong. I have made *** forms incorrect so they cannot do anything. Helplessly, I give up.
*. Two days later(**/**/****) I receive an email, a Legal Intimation Letter from an Advocate of that company (ADV. VISHNU SINGH) saying that I have to pay the registration amount to the company or else I will be charged under Section ** of Indian Contact Act for negligence of payment and Section *** of IPC for doing fraud for non-payment of registration amount. I the payment is not done then the case will be transferred to an Arbitrary court.
*. I call the company's helpline number and the person who contacted me on behalf of the company but none answered. Then I decided to call the lawyer, I called him and asked him the matter regarding the email. I explained my situation to him by telling that I was not told that I will have to Pay any money and that the company was doing a fraud by showing wrong data. He was not ready to listen and interrupted me by saying " Please come to the point and tell whether you will pay the amount or shall I forward the case to the court" I kept on saying that this is not right and its impossible *** forms could go wrong. He asked again if he should forward the case or not. to which I angrily said " I will definitely not pay a single rupee since you all are running a fake company" and he interrupted by saying "Ok" and put my call on hold.

Please look into the matter as I do not want anyone else to fall into such traps and I dont want to pay any kind of money.
