Jet Airways — Money not refunded for cancelled flight

Address:

Dehradun, Uttarakhand

I booked my flight DEL-YYZ on 19th July 2015 PNR: SELDBX and Ticket No:[protected] and cancelled on the same date. They promised my money would be refunded within a week. I still haven't received my money even after innumerable emails and contact on twitter. They have to refund 45000 INR. They don't even reply to emails.
