Hi.
Hello, how may I serve you?
As, My manager didn't approved my leave, so I want to change my reservation. Can you help me with that?
Sure, I will help you. Please provide the name on which ticket was reserved.
Thank you for taking my request into consideration.
Welcome.
The ticket has been reserved under the name of Emily Harris.
Sorry, there is no reservation existing on your name.
Ok, thank you.
You are welcome, have a nice day.
