Can I still claim my labor dues after signing the visa cancellation papers?

I resigned from my company because I had a better job offer.

The previous company did not pay me all the salaries and end-of-service benefits with excuses that they are not doing very well but that in the next few months they will deposit money on my account.

I signed the visa cancelation paper not knowing that it is stated that I received all the dues that the company owes me. Since my resignation, it has passed a couple of months and I still haven't received anything.

The last time when I asked, the company representatives told me that they will not pay me and I can go to court.

Do I actually have a legal ground for a complaint regarding the statement on my visa cancelation paper?
