Recovering salaries from past employer


Hi All, I used to work for a startup an year back. They were not able to pay Salaries from last 10 months so I decided to quit. It’s been now around one year since I am following up with them for my dues. They don’t say NO but they are not paying my salaries too. I have heard that if company shuts down or files for bankruptcy then promoters are not liable. This is a Pvt Lt company registered with MCA. What legal options are with me to recover my dues ?
