I 100% concur.Had them do a complete makeover for my newly bought resale flat.Price was a little steep but same thing had to compromise due to relatively poor overall workmanship.The design proposed was 50% impractical and just want you to do more so they can bleed your wallet more.Lots of hazard for kids with all the sharp corners.The finishing was crappy.Maybe can get better quality from Ikea and for the price you can redo all over again.Worst is the coordination,the ID makes his own arrangements and doesn't keep you in the loop causing a lot of inconvenience.
Recently,I had some warranty from cracked tiles and water leaks to my neighbours downstairs.Initially the ID didn't respond,till I gave his number to the HDB officer then he bo bian had to take action.Once the fees are fully paid,you can expect a total change of attitude from them.Especially when it comes to rework and such.Good luck to them and hope they can improve on their services amd quality else they are going to lose more jobs if words go around.
