Bank Of Baroda — Refund from Amazon is not reflected in my bank account

Refund from amazon has been initiated on 03 th july 2020 regarding a product,
Reference number of the refund is #aoh21wi60000kalodzfb,
But the refund ha not been received yet,

Bank is saying that no amount is received by them whenever i have talked them again, no response is given by bank about my refund,
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 to get my refund reflected in my bank account which was already initiated by amazon, otherwise i have to take some other legal action.

Regards
