Employer not paying final settlement after resignation in Pune, what are my options?

I resigned from my job in Pune three months ago and have been waiting for my final settlement, including salary and bonuses worth around ₹80,000. Despite numerous emails and calls, HR keeps delaying, saying they're still processing it. I'm feeling helpless as I rely on this money to pay my bills. This is causing a lot of stress. What legal action can I take to ensure my employer pays my dues promptly? Are there any specific labor laws in Maharashtra that can help?
