Can my employer force me to work?? (ps-pls read the full article)

Hello, I am currently reside in Mumbai and associated with a firm based in Haryana. I've been working as an Intern in Project development. I've had been associated with an institution based in Mumbai which made me learn computer languages and then proceed towards job placement, where I got selected in the following company. So here are the lies I've been told. Firstly, I was told it was a 6 member company, wherein after I joined I got to know that Its just me and one more. There is no formal structure and agility maintained in the organisation. I started off with the work on June 8th, 2021. Where I've signed the letter of intent on the same date and have been told to read the terms on the appointment letter which was produced on July 6th 2021. Right now, I've been looking for a job as I am done with the management's ill behaviour. On July 6th 2021, I've informed the employer to leave the organisation, as I was threatened by the terms and the conditions which I haven't signed. I just wish to know, how convenient was it to threaten me and force me to stay in his esteemed organisation.
