Myntra.com — myntra.com refund not credited to bank even after 19 days of refund processing message in app and mail.

I returned two items amounting rs.314.40 and rs. 349 and received the message as ' refund processed' on 3/02/2020 with two 12 digit bank reference numbers for two refund transations. Even after 19 days i still did not receive my refund in my account. Bank says 12 digit reference number doesn't exist, it is always a 23 didit arn number. Please accept your mistake and refund me my money, myntra. The return number for rs.314.40 product is [protected] and for tge rs. 329 product is [protected]. Refund my money immediately. I have even mailed myntra my accoumt statement starting from 03/02/2020 till present which clearly shows no refund is credited to my account from myntra.
