What do you expect from the second hand item? It is not your lucky day when you get that faulty item. Accept the consequences once you tested the item during the COD with the seller. If you are not ready, do not buy 2nd hand item from the 1st place. Take this as a lesson. This is lowyat not a pavilion, mid valley or TS mall. Buy a new one if you expect a full recovery of warranty. Move on!
