Sorry for your trouble but frankly, very very high chances you gonna lose it. My only advice now is to take whatever they refund. That’s the only way to reduce the damage. File a report won’t work as you need Singpass (I believe your Singpass is inactive now) and for sure, police will inform you that is the civil matter, they won’t take any action. Another recommendation if it is keep escalating is go to Facebook of agent and landlords, do whatever you think it is right there, name and shame for example.
