I have bought lg 123cm (49 inch) full hd led smart tv (49lh576t) on september 21, 2017. Then i cancelled my order on september 24'th. I paid ₹47, 999. This is not yet refunded. Its been almost a month, since i cancelled this transaction. I tried to contact the so called 24 *7 support. It didn't even connect at-least once. There is no chat support also. Please do the required to refund my money as soon as possible.
