Amazon India — refund of tv amount not done

I am extremeley disheartened with experience of buying and cancelling of lg 43 inches tv in amazon. I purcased tv vide order #[protected] on sept 16th 2020 under exchange policy. Amazon has changed exchange policy before the delivery on aug 23rd and subsequently the order was cancelled on sept 23rd 2020. As per amazon policy the refund of my money would be done on or before sept 29th 2020 however i have not recieved my money and amazon team is giving excuse of delaying another 7 -10 days. I have all the proofs of refund date comittment from amazon. My credit card is due in oct 1st week and i will be charged in my credit card. Amazon has really failed to live to the expectations. I need refund of my money with transaction reference number
