Supertech is the face of builders in India today. This is a product of flawed real estate laws in India. They do not have any moral, ethics and have eye on your money and would say any lie to get money out of your pocket. After booking with time you would slowly come to know about their real story.
Very carefully read each and every line of builder buyer agreement. Although no builder is good in NCR but this is one of the worst. You must go through various discussion forums available online about supertech and you would come to know about their deeds. Beware of this builder. Best of luck!!
