State Bank Of India [SBI] — My refund was not processed by bank

My name is prakash chalamcharla and i had ordered spigen liquid crystal cover case of ₹599 in amazon on 1st june and after 5 june i returned this order due to personal reason and on 7 june amazon initiated the amount to my card but i still didn’t get the money. Amazon sent this reference number 810533 &told me to fill charge dispute form after contacting their customer care. So please kindly respond to this complaint and it’s very urgent to me. My card number is [protected].

Thank you sir
