Canara Bank — I'm complaining about Refund money from Amazon

Dear Sir,
This is my Amazon money transferred initiated reference number[protected].
I ordered an parcel on January 12 2021.My parcel picked up on February 03 2021 and my Money refund initiated from Amazon on 03 2021.But still now I didn't receive money to my bank account. From Amazon side they said, they initiated the money already but the bank(CANARA BANK)is delaying.
