Solution to resign and travel back to home country

Hi Ma'am.

My name is A. K. I am from India. I am working in a manpower supply company.

I came to the UAE on Jan 26.1.2021. My work started on 24.2.2021 and my visa is a limited visa.

But my visa approval after the medical date was 2.6.2021, four months after the company arranged the medical.

Now I gave a resignation letter but they rejected my resignation letter. I want to go to India, what do I do Ma'am?

Please give some solution.
