The employee promised to "save" customers stuck in timeshare-like contracts, for a fee.
But it seems that that promise was just bait to hook customers into spending more money on the company.
Customers forked out between $200 and $14,000 more, but said they ended up being stuck with bigger problems.
At least 11 people have complained to the Consumers Association of Singapore (Case) about the company, The Discovery Group, between February last year , when it was set up, and June.
Consultant Mark Lau, 31, was one of them. His headache started in 2008, when he filled in a survey while shopping at Orchard Road.
A phone call followed, then he sat through a sales pitch for "good deals" on airfare and hotels abroad, and forked out $5,000 in membership fees to a company called Discovery VIII, all on the same day.
"They urged me to sign up on the spot and said I would get a free trip to Krabi," Mr Lau said about the five-year membership.
"It was the complete package, including airfare, hotel, tour. I was swayed."
