Bank Of Baroda — refund matter

Address: Bhilwara, Rajasthan, 311001

A refund has been made by amazon on 22-feb-2020. 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 bank gave no proper response. I talked to amazon customer care and they gave me the refund reference number to ensure me that it is not their fault and the bank is responsible for the refund to me. Please solve my issue.
Refund reference # 152858.
