Ya, agree, best is to check with the ministry or the authority concerned.
However, these slick talkers + ignorant & lazy consumers makes up a perfect cheat :-P
Those who did a bit of research (at least google on other possible options or get 2nd opinion) would probably saved themselves from the scam (like one beautician who just did that 2 days back).
Unfortunately, these group of consumers are usually poor in their command of English or Malay, hence info in these 2 languages doesn't reach them. And too bad I'm a banana, can't write in Mandarin.
