I ordered my headphone from Amazon on 4 April 2019 My order with Amazon was cancelled due to some problem after that they initiated the refund when I asked them they told me that my refund amount has been processed from their side and stuck at bank end ie bank has not credited it into my account. I complained UCO bank with my issue on customer care no. But they have not processed my refund yet.
