Hello.
Hello, how may I aid you?
Due to office conference meeting, I am planning to change my existing reservation. Can you please help me for this?
Sure, may I know your name?
Myself Debra Wilson.
Please give me a moment to check your ticket status.
Sure, I will wait for your response.
Sorry Debra Wilson, no reservation is available by your name.
Not a big problem, anyhow thank you very much for checking the reservation status.
