Indian Bank — Refund not processed By PNB Bank

Address:	Amazon.in
Website:	www.amazon.in

My name is Rajveer Singh Chadha and i had ordered "Magnetic USB 360 Degree Rotation 3 in 1 Fast Charging Data Cable"
Of rupees "425" including shipping,
on 1st November 2020 and cancelled the order due to a personal reason.
My refund was initiated on 1st November 2020 by Amazon on my card but i still didn't get the money.
Amazon sent this reference number "# 5134040307028570199617" and told me to fill charge dispute form but Indian Bank doesn't have such policy.
So please kindly respond to this complaint it's very urgent. My card number is "[protected]".
Thanks you sir
