MakeMyTrip India — I didn't get the actual refund amount

I had a ticket for udaipur to bangalore flight on 19 November and due to bad weather conditions Spicejet cancelled the flight in that case as per the rules I should get full refund but I didn't get full refund . The ticket costed me 8452 rs but they transferred me only 1500 rs. I contacted to Spicejet they said they have processed my airline fare to make my trip but I didn't get full refund from make my trip. They don't have any customer care and they are not even replying on Twitter and email
