Air Pegasus — Refund not processed yet

Address:

Bangalore, Karnataka, 5600001

Booked two tickets from bangalore to madurai on july 27th 2016. The flight was cancelled at the last moment and there was no refund processed. No response from the airline. I want to file a consumer case against the airline. Airline say they have refunded but makemytrip through which i booked the ticket say they have not received the refund yet. I want severe actions to be taken against the airline.
