Jet Airways — After getting pnr not issued ticket

Gentlemen,
My name is Prashant Sehrawat. I am working in Customs as an Inspector in Bangalore. I made a booking from bangalore to Delhi of flight no. 9w820 time 10:30 for the date of 24/03/2016. In this connection I have paid the amount of Rs.4929/- through my SBI net banking which has been debited from my Account. The transaction Ref No. IGOBRTKZM7. But I haven't get the ticket and when I talked to your customers care executives then they told me that the ticket could not be issued for technical issues so the ticket is deemed to be cancelled and they have also assured me that I will get my refund amount within 72 hrs. But still I haven't get any message or mail from your side. I don't have any hesitation that it's a big harassment which is given by you to your blind faith customers.
So solve this issue as soon as possible for your endless reliability.

Prashant
Inspector ( Customs & Central Excise )
