Booked a ticket from salem to vijayawada on 24/05/2017 for journey on 25/05/2017.. The ticket number is oonl469438. I cancelled the ticket on 25/05/2017 at 7am.. But i didn't get any refund.. I am trying to contact the customer care since a week but not able to connect as the lines are always busy.. Two numbers [protected] and [protected].. They say that they have noted my number and contact soon.. But still not received any communication.. Contacted the local office in salem, but asked to contact customer care.. Totally helpless..
