Haven't gotten my salary for 3 months

Hey folks.

I'm working at a small startup, where my salary hasn't been paid for the past 3 months. They've been running low on funds but been getting future timelines which they're not backing at all.

They're raising their another round, but not sure when it'll be done or if they'll be able to close it. I'm already exiting from the company.

They've shared a small date for payment of 1 month's salary on the date I'm existing and the rest seems arbitrary for now.

I don't want to burn bridges and end it on a good note so I have been agreeing to their timelines. But now as I'm serving my last few days, I want to make sure I'm getting paid and they don't default.

PS: My PF account was not created by the employer.

What are the actions I can take to ensure I'm getting paid?
