Punjab National Bank [PNB] — Amazon refund amount not received from bank yet

Website:

AMAZON INDIA

Dear Sir,

I Miss. Anusaya Sahoo, bearing the Punjab National bank account No. [protected] having the PNB rupay debit card no ending with 8341 have to say that I have done two online transactions through Amazon website through the above mentioned PNB debit card.
Later due to product quality issues I had to cancel and return both of these products to Amazon .I also got a successful refund message from Amazon.
Amazon has also provided me with the refund reference ID for your kind information. but it's a matter of regret that My own bank PNB couldn't process the transaction yet. However, the refund reference ID clearly stated that an amount of Rs. 3721 and Rs. 449 has already been received by PNB Bank.

AMAZON INSTRUCTED ME TO CONTACT WITH BANK IMMEDIATELY BY SHARING THE REFERENCE ID. MENTIONED BELOW:

1.Refund Reference # 30005120912091083666606
Amount: Rs. 3721

2. Refund Reference # 30005120852085123400135
Amount: Rs. 449.10
Refund Date: 07/04/2022

But unfortunately PNB bank simply ignoring such issue and taking lightly. I have already put complaint several times at PNB bank. But Bank is saying no refund received. As its a RBI refund reference number, Bank can not deny this. Because this is the confirmation reference to amazon that bank has received the amount from amazon.

kindly help me sir.

Regards.
Anusaya sahoo
