My ex-employer is always finding excuse to pay our end of service gratuity

My ex-employer is always finding excuses to pay our end-of-service gratuity.

It's almost six months now, and still, they are not committing. And every time I talk to the human resources manager he always moves dates for releasing my pay of settlement.

I wanted to call the ministry of labor but on the other hand, in respect, I have not raised a complaint against them yet.

I am also worried as I've already signed my cancellation and I need to join my new company to apply for my new visa.

Is there any way or process through MOL?

If I raise a complaint, should I get a lawyer?

Hoping for any advice.

Thank you.

God bless you all.
