Hello.
Hello. How can I assist you?
 There is an emergency case which came to hearing on the dates which I have planned to enjoy in my holidays, so I am unable to travel the trip due to this one. Can you please help me in changing my flight ticket?
Sure, can I know your name please?
Sure, I am Samantha Lopez here.
Ok, wait a moment please.
Sure.
Sorry Lopez, there is no reservation found on your name.
Ok, not a problem.
Thank you for approaching us.
