Hello. I am John Campbell.
Hello, how may I aid you?
I made a reservation earlier in the wrong date unknowingly so, I want to change my existing reservation. Can you help me with changing?
Sure, please wait a moment I will check your details and proceed further.
Sure.
Sorry to say, there is no reservation on your name in my database.
That's alright, thanks for your assistance.
Thank you for reaching us, have a nice day.
