When Malaysian teenager Ah Heng (not his real name) saw a Facebook post in February advertising a job for a customer service position in Cambodia, he was intrigued.
The job promised him RM4,000 (S$1,250), which was more than what Ah Heng, 19, earned monthly as a phone shop assistant back home.
But it was the beginning of a three-month ordeal during which he would be forced to work for a transnational scam syndicate, which allegedly stole millions of dollars from victims.
