I have bought a property from builder in sonipat, haryana. Builder has launched property as villa only complex and later changed the nature of property and made it hybrid living and sold personal floors and plots in the same complex. Whole project is delayed and builder has demanded extra charges on account of increase in area, which is of no use to customer, it's only on paper calculation. My property is also devalued as floor is coming up in the same complex. I am looking for legal option to sue builder for changing of nature of property and remove all unnecessary charges, which has not been agreed by customer.
