Just had Teng Yong curtains pte ltd over at my place to take measurements that prompted me to do a google search regarding the integrity and reliability of this company. For the record, they quoted me roughly 600+ for living room curtains, one master bed room (mind you, we have an extremely tiny window for the master bedroom, and roller blinds for the other room.) Having compared the quotations from a few companies, they offered us the most attractive price and thus 'locked down' the expo price by paying a $200 deposit. After today's quotation, we were required to pay a total of $1572!! THAT IS DOUBLE OF WHAT THEY QUOTED. In the end, we had no choice but to proceed and change certain things to reduce the price. After reading through the comments and reviews on google, im certain that this company operates through such scams . So beware of them if you happen to see them at any renovation fairs. Infact, DON'T even bother asking for a quote.
