Do I have to give a notice that I am not willing to renew my labor contract before expiry?

Hi,

My visa is for 3 years and my contract is a 2-year limited contract. My contract expired on Feb 17 and I didn't get any info about contract renewal and cancellation from my office.

Due to health issues, I resigned on March 13 and presented my medical report to the office. The manager informed me I have to serve the notice period but no need to go to work only after the completion of the notice period date they will process the cancellation.

Now they are asking for visa money they are telling me my contract got auto renewed and I need to pay. I should have resigned 30 days before my contract expiry date. I already finished 2 years

Do I have to pay any money and will there be any problem as I didn't attend the duty in my probation as the manager told me only by word not to go to duty?

But I mailed about my condition and my medical report

As I enquired, our company comes under Al Aweer immigration and Taseel has no info about my contract or any info. Where to get more info and guidance?
