Hi.
Hello. How may I aid you today?
I am George Taylor.
Ok.
I want to change my reservation due to postpone of my appointment with doctor at Philadelphia. Can you help me in my changing reservation?
Sure.
Thank you.
Please wait for a while, I will let you know.
Sure, I will wait for your response.
Thanks for your patience, but no reservation is found.
That's ok, thank you so much for your service anyways.
Thank you.
