Hello.
 Hello, How exactly I can serve you the best today?
Owing to an emergency I had to request for this change reservation. Can you please help me to change an existing reservation?
Sure, may I know your good name?
My name is Pamela Wilson.
Give a minute, I will check the previous list and let you know the details of it.
Sure.
Thank you for your valuable time. No reservation found on your name.
That's not a problem. Thank you.
Thank you for reaching us, have a good day.
