Amazon India — An old Micromax TV 32 inches sent instead of my order LG 32 inches

I ordered an LG TV 32" on 30.12.2020. I received it on 09.01.21. The LG TV mechanic came to my house for installation
and saw that the TV sent by AMAZON seller was an old MICROMAX TV 32" without remote. I contacted the Amazon service representative on the spot and sent a photograph of job sheet by the mechanic.The representative sent a request to refund the purchase value as early as possible . They will pick up the wrong product and the refund process will be initiated. Six times the customer care has given me messages of picking up but failed every time. I am in anxiety about my money and time. I am not able to leave my station peacefully.
