I am one of the many highly dis-satisfied customers of Kumar builders(KUL or KB). The story seem to be similar at many projects. We got the posession of our apartment in Kumar Shantniketan 6 years after booking. Posession was just a formality, the premises are not livable even now but customers are forced to move into the the same dangerous premises(which have open trenches through which the kids/elders can fall into the basement parking besides several theft and other instances).
Anybody who wants a home should not buy anything with Kumar. Write to any of the customers on yahoo group of kumarshantiniketan@yahoogroups.com and you will get the true story of Kumar builder.
