[Resolved]  Techno Enterprise — agreement without acceptance and levy of charges

Address: Firozabad, Uttar Pradesh, 283203

I had applied for a job which is to be done from home. I got a call from Techno Enterprise. They asked me to complete 10K captcha codes in 10 days. If I failed to complete the task or withdraw without completion, I am obliged to pay INR 5K. I accepted the same. I submitted an ID proof and photo of mine alongwith my signatures on a blank paper. After few minutes, I got an agreement on INR 100 stamp paper containing my photo and signature. That agreement has been entered into without my acceptance.
Later on, I came to know that many complaints have already been filed regarding the same issue. So i decided not to do any task and therefore didn't commenced the task. Their representative told me that I may cancel if i dont wish to continue by telling my final decision on a call from company's side without paying any charges. But when I did the same, the company asked me to pay INR 4K as fees to use the company's software.
From then I blocked all their calls and SMS's. Now, after 10 days I have received a mail regarding my obligation to pay from their advocate associate. Whether I am liable to pay anything to them.
Pls reply ASAP. I am in urgent need of your help.
