Jet Airways — unfair deduction for cancelled flight

Address:

PV Nair C/O Mr Jagdish Chandra Sharma H.No.9 Street no.4 Near Chawla Hospital, Hanumangarh, Rajasthan, 335512

Sir/madam,
I had booked a jet airways flight ticket on 12/03/2019 for journey which was scheduled to commence from new delhi (Del) to kochi (Cok) on 12/04/2019- vide booking reference (Pnr) no: jsdkdz and flight no:9w 0912, e-ticket no:[protected] and[protected]. I had paid rs.8752/- towards the flight charges.
The above flight was cancelled by ja itself on the 16th of march. While making inquiry with the customer care on the 17th and 24th of the last month about the status and amount of refund, i was told by the concerned authorities that the total refundable amount is rs.8752/- and the entire amount of rs.8752/- will be refunded without any deduction - though the convenience charges will not be mentioned in the refund receipts (Which were mailed to me on[protected]. Yet, an amount of rs.8302/- only has been refunded on[protected] after deduction of rs.450/- which is beyond my comprehension. This is in no way right, fair and justified. Why passenger should suffer financial losses due to cancellation of flights by the airline companies itself? Instead of making any deduction from the paid fare, airline companies should compensate the passengers for the financial losses - as in my case, i had to cancel onward train booking also - due to cancellation of jet airways flight.
Airline companies impose heavy penalties for cancellation if requested by passenger himself but if flights are cancelled by airline companies itself - causing a lot of inconveniences, entire fare should be refunded. There is no justification in withholding a part of the fare paid.
In this connection, i had sent a mail to customer care on the 9th of this month - seeking clarification regarding the deduction, but the mail is still lying unanswered.
I had sent a mail to nodal officer and appellate authority also - on[protected] at [protected]@jetairways.com (Nodal officer) and [protected]@jetairways.com (Appellate authority) but delivery to these recipients failed due to the addresses being wrong. These addresses were taken from google search - since address of both these authorities are not available on jet airways site.
Kindly requested to look in to it and do the needful and help resolve my problem.
Thanks and regards
P. V. Nair
