Woah! That might actually be my fault..
I am rushing for renovation too and the person-in-charge of my unit is Mr Koey... Maybe due to our good connection, he probably have prioritized some of the men power for my unit. I believe it is possible that the construction people from your unit was transferred to mine... That is probably the reason the problems for my unit was rectified in a very fast manner.
I agree on your concern for the water leakage issue. I sincerely hope that the problems won't occur again in the future. However, to be fair, water leakage issue is hard to predict and prevent but at the very least, they are patching it up.
madtalk, I believe you are very new at this. At least when it comes to luxury property. Thus, the property's progression is at the top of your concerns. Honestly, I need owners like you to share the problems here in order to monitor my property as well. Having experiences managing a number of properties, I noticed that when there are too much complaints, you tend to bring Bad Chi into the place as well. I practice Buddhism and Feng Shui, so this is very important to me as I believe that by doing so, you will end up not being happy with the property no matter what. Complaints are good but let's not put negative Chi because that won't bring luck to the property. Be positive and let the people in charge do their job. We just to find the right person and the right channel do get things done. Give it time as the contractors are already trying their best to help us out.
I find Mr Koay to be very helpful. Thus, if you are sincerely keen on fixing your properties, I will pass you his number and request for him to give you "special treatment". Haha! My wife hates talking to him but I know how to handle him in a proper manner. Hehe

Whatever that has been done, cannot be undone. However, the fact is that these constructors are currently fixing the damage. Sometimes, we have to look at the bigger picture and reflect. There are about 300 owners, all of which are rushing at the same time. So we have to compromise with the delays as the constructors have a lot on their plates, closing one eye. Just, make sure that at the end of the day, you are satisfied with the house.
The 24 months warranty you mentioned applies to all industry. Like cars, you buy Proton -> breakdown -> send to service centre for 2 weeks repair. Lets assume they take their own sweet time, so you complain to the max. They provide you a courtesy car to drive until it is ready. You shouldn't expect that they would extend your warranty for 2 more weeks. They wont entertain your complaints and you shouldn't bother. This happens in all industry. No choice.
Now, what I suggest is for you not to bother about other units. Ensure first that your own unit is fixed until your satisfaction. Remember, the right channel and the right people would bring good Chi to your property. Don't spread your bad Chi, as it would affect others as well.
I believe I am bringing good Chi to the property. I give my trust to my constructors. Although, sometimes dealing in Bangla construction area can be difficult as some of them are uneducated. This kind of things need experience.
Let's ensure that everything is resolved in a nice manner.
* is REALLY BAD! if I see Villamas director, I will complaint this too them. You want to FIRE all of them???!!! HAHA
project team - poor follow up
admin ppl - not replying emails and phonecalls
at the end of the day Mr Koay is only working for Villamas and both him and Villamas is trying their best to rectify the problem..yelling and cursing will not solve the problem but may lead to more argument and delay...
sit down and talk nicely and list down all the defects in 1 go..set a win win deadline so that everyone will be happy..fair??
