Please beware of Teng Yong Curtains at Expo. I have very bad experience with them. I recently paid a deposit during their expo fair to lock down "expo prices" which are supposedly really cheap and a discount after the final amount. However, during the appointment, they (different guy from the expo salesman) turn their back on the promise and refuse to give the discount, claiming the expo price is already very cheap and would at most refund us the deposit. When we call their main office to ask for the refund, they refuse to refund the deposit. After many phone calls and couple of day, they finally agreed to give us the discount. By this time we have already lost all our confidence with the company for all the unnecessary stress and time wasted. We now only want them to do partial based on the lock down price and was now told the "expo prices" is for whole house and individual rooms prices will be almost 50% higher and a installation charge of $150. However, the admin of the company told us the installation charge is $120 and another sales guy told us they can waive installation for total amount >$500. This shows much about the integrity of the company in charging their clients.
