Bank Of Baroda — refund not credited from amazon

Refund of rs. 1074/- has been made by amazon on 03rd of january 2019 regarding a product (Order number is #[protected].
"the reference number of the refund is ref - 75503720003036562251106.
But, the refund has not been received yet.
Bank is saying no amount has been received by them. I've talked to them again and again but no response is coming. So i need to file a"charge dispute" on them, to get the full details.
I need bank to resolve this issue as soon as possible or i'm gonna take some legal action.
