Indian Bank — Refund Not Received For 3 Years

Address:

Nerul, Navi Mumbai

I Ordered 2 H&M Hoodies from Myntra Which Were Priced 1034.10 Each So The Total Price Was 2068.20. I Ordered Something Else With Them So The Total Amount Debited For The 3 Products Were 2602.80 But The Order For The Hoodies Got Cancelled From Their End(No problems with the 3rd product) And I Only Got A Partial Refund Of 1034.10 & Didn't Get The Refund Of The Pending Amount Of 1034.10 Till Now.
The Refund Was Processed on 13th July 2020 Which I Confirmed With One Of Myntras Executive.
I Used PayPal For The Transaction And In PayPal I Can See Both The Refunds Being Processed.
But When I Went To The Bank, They Said The They Haven't Received Any Refund From Myntra.
It's Been Almost 3 Years I Haven't Received Any Refund, Please Help And Kindly Look Into The Issue.
