Hi.
Hello, how can I amend you?
I want to change an existing reservation due to sudden change in my trip. Can you help me?
Sure, I am here to assist you. May I know your name to check the reservation list?
I am Alexander Evans.
Please stand by.
Ok.
Thanks for waiting. I have checked in reservation list to change your ticket, but could not find any reservation with your name.
No issue. Thank you.
Thanks for your approach.
