Hello.
Hello, how can I assist you at this moment?
Actually I am trying to modify the details in my previous ticket which is booked in the last week but due to some server problem I am not getting that. Can you please help me in changing?
Sure, I will help you with that. Can I have your  good name please to check your  reservation status?
Thank you for considering my request. My name is Joseph Thomas.
Ok,  please wait a moment.
Ok, take your time.
Sorry Joseph Thomas, no reservation has found under your name to change.
It's ok, not a problem with that. Thank you for checking the ticket status.
Thank you for choosing us, have a  good day.
