For the time she was cancelled she supposedly reported or complaint to Labour Department in Industrial Area Branch to help her for this matter so atleast the action was implemented. If theres no valid reason of cancellation, written warning or a month notice. she have the right to claims whatever dues to her. if no NOC there should be ticket back home, end of service entity, yearly leave, a month of notice and compensation whatever stated on the contract. She have to seek a good advice from the labour first to make things clear.

Goodluck to your friend.
