Hi.
Hello. How may I assist you?
I'm Anna Adams.
Nice to meet you Adams.
Due to sudden change in my schedule, I want to change my existing reservation to some other dates. Will you help me in that?
Sure, please wait a moment I will get you back to your status of reservation.
Ok.
Thanks for your patience, but there is no reservation under your name.
That's ok, thank you for searching.
Welcome, have a good day.
