Ibibo Group / Goibibo — Refund for flight booking

Goibibo has not refunded me the amount of RS 5000 that has been already refunded by Indigo.
I made my flight tickets booking via Goibibo where due to some mistake from Indigo they cancelled our ticket, but the moment they realized their mistake they initiated my refund i.e on 26th September to the third part which is Goibibo here. Its been almost 20 days now where I have been trying to connect with Goibibo be it Mail, Facebook, customer care number, Goibibo App, Instagram but they are not clearly responding on any of them.
I need my refund asap.
