[Resolved]  Punjab National Bank [PNB] — charge dispute, refund not processed, refund reference # 930514

Address:

Gureghar, Bishnubati, jamalpur, Purba Bardhaman

I order some products from amazon and order cost @711 placed on 14/05/2020 and done full payment by pnb debit card but order was cancelled on same day 14/05/2020.
I did not receive my money back after the order was canceled.

I contacted amazon's service center more than once and they told me, refund has been send to bank successfully processed on[protected] please wait a while.

But now amazon is saying that refund has been send to the bank, please contact your bank’s customer care center and quote with refund reference #930514 to know further about the status of the transaction in case you still haven’t received the credit within 4 business days.

I called the helpline number of the bank but my problem was not solved from there,
Then i call to amazon's service center and they told me this time,
#if your bank is unable to locate the refund with the reference number provided (# 930514), please dispute the transaction as 'refund not processed'. At that time, they will see a pending refund and will follow the path back to our payment processor to locate the refund...

I contacted to the bank customer care and they told me clearly that there is no such thing like charge dispute form as refund not processed, we can just check money credited or not.

Since then i have been very worried about how i will get my money back. Please help me.
Thank you
