How to claim unpaid wages?

I joined Blupin Technologies Pvt. Ltd. (Mylo) on 19 January 2026 as a Performance Marketing Associate and worked there until 3 February 2026. On 4 February, I informed my manager via WhatsApp that I would not be continuing with the organization because I did not see suitable personal and career growth opportunities. At that time, due to a family emergency, I was unable to visit the office to return the company laptop, so I sent it through my cousin, which was acknowledged by the team. Later, when I asked about my salary for the days I worked, the company refused to release it and marked me as absconded, stating that I did not follow the formal resignation process. However, I had already informed them and returned the company property. Additionally, my UAN was linked with the company, and PF contributions were deposited. Despite sending emails and contacting HR, they have refused to release my salary for the days I worked. I would like to know my legal options to claim my pending wages.
