Employer not paying dues

I was employed by a Company at their unit as a General Manager in August 2022. They did not issue an appointment letter or an offer letter citing urgency and stated that the corporate structure is being established and will soon be issued. I had taken charge on thr basis of mutual understanding since it was through a strong reference. A month later they issue a 'Letter of Intent' which had a paragraph reading i am being appointed as General Manager of the said unit at a gross salary of X amount from this date. The pages had requisites of credentials to be submitted followed by medical requirements. No clause for transfer, code of conduct, probation, termination, notice period clause, annexure of salary break up or anything related to a proper Offer letter. Six month after, January 2023, the company decided to shut operations and unit and stopped all communication stating the unit is closed through verbal channels without any form of notice to me or other employees. They did not release any salary for the remaining month (December 2022), vendor payments and dues stating in an email through Executive Vice President that they need the employees to pack all of their capital goods first, dispatch it to the other unit in another state, share the transport waybill and only then will the payments and salaries will be released. During the tenure, they did not share any pay slip but payed through Salary accounts opened under the primary company profile for all employees including myself. They also held salaries for employees in the month of December for November for unknown reasons. When i enquired about it, they said it is due to some accounting discrepancy but, there was no communication in regards to the same. They released the salary after twenty days. I left the unit and returned to my hometown after, I had communicated the company through email citing my safety and security is at stake due to sudden shut down of the unit without due diligence and non payments of dues and that thr decision by the company was immature and against professional ethics. Now, the company has not paid me or the vendors or the remaining staffs citing that their capital goods have not reached them, they have declined to revert to my communications and have shared no information in regards to the status of my employment. What should be my ideal step? I would appreciate any advise pertaining to the above.
