I was employed with a company for more than a year, during which I signed a 1.5-year contract with terms that were not legally sound. The poor work-life balance and lack of adequate salary increment led me to decide to quit. I submitted my resignation via email, but it was rejected on the basis of my contract. Despite this, I announced my final working day and served my notice period before leaving. Currently, the company is withholding my remaining salary, experience letter, and salary slips. I have written numerous emails and have even sent a legal notice, but to no avail. I am hesitant to take this matter to court. Is there another option? I have considered editing another person's experience letter to include my name, as I did work there. However, I am concerned about potential repercussions later in my career.
