Delaying visa cancellation and payment of dues upon resignation

Hello Sir!

I worked as a Logistics Coordinator from Sep. 2017 - Feb. 2018 in a free zone company in Dubai.

I resigned with a 30-day notice before my probationary period ends because of unpaid salary and my employer accepted my resignation.

It's been 5 months since I left the company, but my visa has not been cancelled by my employer which is fine for me as I am still looking for a new job as at this time.

My previous employer did not pay me my last 2 months' salaries and has not responded on any of my follow-ups.

My question is at the time that I get to find a new job and need cancellation of my old visa, what if he does not respond?

Will the free zone company still cancel my visa even without my old employers NOC?
