Ibibo Group / Goibibo — Refund amount not correct

I had cancelled my flight from mumbai to bagdogra (Scheduled 21/06) because the airline cancelled the bagdogra to mumbai flight (Scheduled 20/06).

The airline informed me that the entire amount would be refunded for both the tickets.

However, i have not received the refund amount of mumbai to bagdogra flight. The airline told me that they have already credited the amount to goibibo. However, the gia app in gobibio shows that a refund of amount 0 was initiated.

There is no way i am able to reach any sales representative.
