Claiming the labor dues after working in India for a UAE company without contract?

Hi ma'am,

A company has released an offer letter to me to work in Delhi for interior projects. I joined the organization in Delhi and worked on 1 project which is nearing completion and is in the handing-over stage. As there is no office in Delhi, I was working from home in Delhi. No joining formalities were made.

As the situation was getting difficult day by day. I asked them to allow me to work from my home town (approx 3k KMs from Delhi), they said Ok but no work was assigned nor they were making my salary payment even for the month I worked at Delhi.

To join this company, I have resigned from an organization where I served for 5 years 6 months.

Please suggest the way forward to deal with this issue, please!
