How to act against delay of hiring process and threatening to bear overstay penalty

Hi,

I am a female physiotherapist and I got a job offer from my facility on October 15th 2020, after which they delayed the medical licensing process until February.

I got my licence activated under their facility on February 21st 2021 and again they delayed the joining process and they asked me to cancel my visa (spouse) on March 21st 2021.

My grace period will expire tomorrow and they want me to take a visit visa now or they will cut the penalty from my future salary. What am I supposed to do?

Also, I am not willing to pay a penalty as it's not my fault and a visit visa can't be taken as my husband has already lost his job.

Please give me an advice.
