After flat booking they don’t give attention what you say. Sales people would listen until flat is booked and doesn’t bother to answer you afterwards.
The only thing they care about is your money. They would not make any single modification. Not even single wash basin you cannot put in the dining because of mivan technology they are using which is only beneficial to builders not to any buyers seriously. They completed 5 floors in a single month to get maximum money from customers. High tension wire in middle of the project, its not definitely safe.
Think 1000 times before you buy a property from them.
