Air Pegasus — No refund against cancelled flights by air pegasus

Address:

Bangalore, Karnataka, 560001

I have booked four tickets for travelling from kochi to bengaluru on[protected] through air pegasus flight no. Op110. The airlines on a later date cancelled the flight and even after three months, i could not receive the refunds. Like me, there are so many others waiting to get their hard earned money. What is this happening? There's no instrument in india, who can take up the case and get the refunds to genuine passengers?
