How to let my employer cancel my visa at the immigration and take another offer?

Dear Sir/ Mam

Pleased be informed you that after 30 days of my resignation letter, the company canceled my visa in labor but they are not canceling my visa in immigration and did not give me my passport back.

I got a job in another company. What should I do?

I called my employer and messaged him to cancel my visa in immigration but they are not responding to me. They just saw my messages and ignored me.

I go once a day to my company to talk about visa cancellation because they are not replying to my messages.

I told them to cancel my visa in immigration because they already canceled my visa in labor on 11/06/2022. They did not respond seriously to my matter.

So kindly guide me on what I should do. I shall be very thankful to you.

Best Regards

M. A.
