Hello.
Hello.
Ronald Jones here.
How may I aid you, Jones?
  Recently, I had booked a ticket to visit my daughter who is studying in other city, but, due to some reasons I need to change my reservation. Can you please help me out?
Surely I will help you, please hold on.
Ok.
But, there is no reservation found on your name in our database.
Ok, thank you for checking my reservation status.
Thank you so much for using our service.
