I often receive such calls in SG, from the Immigration Department or ICA.
The blogger cleverly judged whether the other person was really from Shanghai/Wu dialect area by the accent, and then found the flaw. But in SG, it is difficult to judge by the accent.
However, when I tried to talk to him in English, he was immediately exposed. I could tell that the scammer really couldn't speak a word of English🤣
Later I learned that the boss of the park was said to divide the group, and the scammers who could speak English were all assigned to the American and Indian groups (the salary was higher), and they would not make phone calls in the Chinese group...
In addition, the real Singapore customer service seems to be all Indian friends...😂Everyone who is overseas should be more vigilant! In addition, if you encounter a scammer again, you can try to speak a few words in English.
