Sir, I Purchased a LG Micro Oven on 02/01/2015,and LG installed the same on 03/01/2015.On 04th Jan 2015,I found that the plate inside s not rotating,I immediately called LG C.Care and Lodged the Complain.The same day person came and inspect the Oven and said that in 2-3 days it will be repaired.But its Now 13th Jan No person came to fix up the Oven.When I called them on 6th they said they are waiting for approval from Quality Department.Now its 8 days over they still not received the confirmation.So what Should I do?????
