MMT - Very bad experience. Review on Makemytrip

I booked a ticket for Mumbai to Chennai on GoAir through their agent MakeMyTrip. Due to health reasons I cancelled the booking before time stipulated by GoAir and they promptly refunded INR 3, 593 to MakeMyTrip for paying me back.

One month passed MakeMyTrip did absolutely nothing, nor did they reply to my emails. Finally I wrote back to GoAir and this time for a change MakeMyTrip responded promising action within 24-hrs. Again, time passed but they did nothing. My brief reminders were ignored by MakeMyTrip as they had eaten up this amount of INR 3, 593 refundable to me.
