I have booked round trip ticket from chennai to melbourne in malasiyan airlines through clear trip site. Due to domestic reasons i cancelled my ticket yesterday 5.12.2019. Today i received a msg from clear trip that thr refund amount is rs 0.00.
I was shocked to receive the msg as this was a refundable ticket. And in the ticket which i received thro mail, nowhere mentioned as non refundable. After checking this only i cancelled my ticket. When i spoke to customer care before cancelling my ticket, mentioning the trip id, i was told that i will be loosing only around rs 9000 for this ticket (To & fro).
But as a bombshell i got rs 0.00 as refund. At any cost i need my refund as per the customer care person assured (Ie my ticket fare minus the cancellation charges around rs 9000/- action should be taken immediately and refund the amount in 24 hours
