Bank Of Baroda — refund amount not created

Address: Yogesh Chhimpa S/O Ratan LAL Chhimpa chhimpo Ka mohlla, G S road bikaner, Bikaner, Rajasthan, 334001

A refund has been made by amazon on 23rd of march 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. I've talked to them again and again but no responss is coming. So i needs 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.
