Consumer Redressal

Hello, I took possesion in aug 13. According to the Parking plan attached with my agreement (signed by Builder), there should be 2 parkings in front of lobby. But in construction he has not built required slab and hence he has accomodated those parkings in lesser space. Due to this there is no space left to pass by. If all the parkings are filled then from lift / stairs one has to make way in between two cars. Even accaording to original plan there was space to move around in front of Electric Meters, but due to this wrong construction, Car has to be parked touching fencing of meter. When asked to Builder , he is asking our authority to ask question. Can we raise this complaint against Builder as resident of that building?
