Bank Of Baroda — refund against my amazon order

Refund of rs. 801/- has been made by amazon on 16th of february 2020 regarding a product (Order number is order #[protected].
"the reference number of the refund is ref - # 74332740047004652363740.
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 responses 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.
