Bank Of Baroda — status of my refund

I want to know the status of my refund.
I have purchased an item from amazon and due to some problem i have asked for the refund of amount 799rs from them. They said they already made the refund on 19/07/19 n it should be reflected by 30/7/19 in the account. But it's been 3 months still the amount has not been credited in my account.
