Flykingfisher — Tickets amount of cancelled flights not refunded

Address:

Bangalore, Karnataka

I booked two way return ticket from Bangalore to Delhi on 18th sept 2012. Due to non-operation (kingfisher employees strike) of kingfisher flights, my tickets were cancelled by kingfisher.
Here are the details of ticket booking:
PNR: NZPCGM
Ticket No.:[protected]
Flights:
1- Bangalore to Delhi: IT208, 18th Oct 2012
2- Delhi to Bangalore: IT201, 25th Oct 2012

I have been requesting kingfisher to refund my ticket amount, but didn't get anything. I have called their customer service center many times, they just keep telling me it will be refunded within 10-15 days every time I call them. I have also communicated with them through e-mail, but didn't get any satisfactory response from their side.
It been more that two months, but kingfisher hasn't refund my tickets amount.
