Date of Transaction : **/**/****
Mode of Transaction : UPI
Account Number : xxxxxxxxx
Amount debited : *****/-

due to CORONA , Flights were cancelled and GOIBIBO has initiated the refund as per the below mentioned details , but amount is not yet credited to my account.
Date of Refund initiated : **/**/****
Mode of Transaction : UPI
Account Number : XXXXXXXX
Amount refunded : *****/-
RRN Number : ********
I have provided the above details to my bank, but they are asking accurate information from GOIBIBO , like
*.Complete details of transaction with time ( Please provide Screenshot/pdf)

But GOIBIBO is not responding to my mails or there is no proper customer care for escalating the matter.
