How did she resign? Did she sent an official email or a formal letter or just an oral resignation?

Did not they put a cancellation stamp on her passport before she fly?

I had a six years contract with an employer in Dubai and I breached it after 2 and half years. They put be me on year ban instead of six months but the Labour Ministry they asked me that I am aware of the ban period , did u get your final settlement etc etc.

Did not your friend go through all these legal procedures?
