Sdmc — Illegal construction in garage

Address:

H2/122,3RD FLOOR, Mahavir Enclave, Palam Dabri Road, NEW DELHI

Our builder Mr. Naval Kishore (Landkraft builders) has built an illegal storage godown in our garage for the past 8 years and has assured us time and time that he will break it to make way for our parked vehicles but haven't done so in these years. Now when we go to him he talks very rudely and tells us to sit tight as nothing will happen. Please Check asap.
thank you.
