IDBI Bank — charge dispute for refund reference number:[protected]

Dear sir,
I would like to inform you that i have made a payment by cash of rs.425 on amazon.in on 19 january 2019 which was later cancelled and refund processed by amazon on 24 january 2019 of rs.425.
My refund reference number is[protected].

Taking into consideration normal working days it should have credited into my account statement couple of days back itself which isn't the case till date, so i request you to "file a charge dispute" with "refund reference number:[protected]".
Request you to kindly resolve the matter and credit the amount back into my account as early as possible.
Looking forward to your reply.
