Shop around ... Before purchasing from "Changi Recommends"

On arrival at Singapore International Airport on the 19/4/19 @ 5.30am, exhausted and tired after flying 11 hours. CHANGI RECOMMENDS consultants **** to us, by saying that they are the cheapest, and we should buy all our attraction tickets from them. We purchased all our tickets and went to have breakfast, only to realize that a few metres away from them, the tickets was much cheaper. I took a pricing pamphlet from them, and produced to them, when we went back for them to call us a taxi, which we paid for. There were different consultants on duty, who after speaking to a Mitchelli from the office, promised the difference of 25 Singapore dollars will be deposited into my account by Friday 22/4/19. They delayed me 1 hour.... Going back and forth. As of today they did not give me my money.

Please we aware of this company, situated at various airports. When purchasing at airports. Also they called me a "Grab" (similar to uber) and charged me 200% more.
