Bank Of Baroda — refund problem to amazon

Address: Village and Post Halor Teh Maharajganj Dist. Raebareli, Kanpur, Uttar Pradesh

A refund has been made by amazon on 17 october 2018 regarding a product which i've buyed from the amazon. But the refund has not been received yet. Bank is saying no amount has been received by them. But amazon says we have send ammount in your bank account..
I've talked to them again and again but no responss is coming. So i nees 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.
