What did he do ? Take your deposit and ran away ?

Very well said based on the trust worthy of the Indonesian workers. Before any one us award the renovation job to this people, have we ever thought of this ?
1. Who are we dealing with ? - illegal immigrants workers who doesnt pose any valid documents/permits
2. A man does not even have language skill to able to communicate in terms of drawings, paper and verbal and yet we can trust them on mutual basis.
3. A man that does not even have a valid company, CIDB license and even passport ?? That's where the 6P being implemented.
4. They are qualified to build under supervision by person in trade. Even people like us owner does not have the rightful skill to do the supervision.

At the end of th day, we can blame them but also we have to take some responsibility for trusting people like them. Because 'we thought we can save money by asking Indonesian to do ma, their boss Chinese but is the Indonesian worker that is doing"
Im terribly sorry for ur mishap ..
Ps: try to trace him at the immigration department, if he has got his thumb printed.
