I have purchased airticket on 3rd of December from sxr to Auh from my debit card and on same day I have cancelled because the ticket provided to me was given wrong timings and details .I wa's been told by them that refund will happen within 10 days .but it's been more then 1 month nothing has happened and I have written to them more then 8 time's and several reminders but no response has been provided.this is pathetic and Un professional organisation which had lost the ethic of communication.
