Hello Sir good evening, regarding on my passport....

Hello Sir good evening, regarding on my passport. I'm a housemaid with 2 year contract and my contract has done and my visa has already expired on July 30. My employer confused me of returning back or sending me outside for release. Now she decided to send me outside because she don't want to afford the ticket. I've found another employer who's willing to take me but my madam doesn't want to give me my passport back. They already file cancellation for the visa. Now I'm only using the grace period of my visa. What should I do Sir?
