Asus India — received a faulty product

Address: Kottarathil, Mammood, 686536

Asus cheated me by sending a faulty device and now they are delaying their service. My gaming laptop's display was not working within 14 days of purchase and when i give it to asus service center kottayam to claim the warranty they assured me repair within 3 days and now they are telling that they don't know when it will be repaired. They are saying that spare parts are not available and i should wait for indefinite time. Its not my fault for their lack of spares. I want a replacement if they cannot service it within the assured date. I gave my laptop for service on 19 october and its been so long. I can't wait more than this or else i need a another laptop to be used in this mean time. My rma number is inxwka0135
Also the service guys in kottayam is behaving improperly.
