Mr. Arjun,
I disagree to you because the problems that you have mentioned I think can be sorted out very easily and this is the place where we are going to stay for rest of our life. So I request you not to escalate this kind of problem on this kind of community site as our project is getting bad publicity in community. It would be better if you solve these problems on site itself because its not gone solve your problem on site anyway. Just have some patience and let them complete our project. And by the way, I think the quality of the flat in my case is as per standard system.
