Ibibo Group / Goibibo — Have not received my Refund

I have booked a ticket for booking id- GOBUSMOBBF8C0EAFC8
PNR - 87QHFP5J
Snemita Paribahan(Digha to Kolkata) on 4th July 2022
at 12:50pm
But all of a sudden bus operator canceled the ticket due to breakdown of the bus.
But still now I have not received my refund. I tried to contact to all customer support of Goibibo.
But seems like they don’t have any interest on this thing. This is such a ridiculous service from Goibibo .
As I am very old customer of Goibibo. I just want my refund back as soon as possible. They promised to call back but they have not.
Such a poor service.
Kindly refund my amount.
