HI.
Hello, how can I help you today?
I made a reservation earlier in the wrong date unknowingly so, I want to change my existing reservation. Can you help me in this?
Ok, I can help you to make it easy.
Thank you.
Let me know your name first to check the status of your reservation?
I am Janet King.
Sorry, we did not find any reservation on your name.
It's ok, not a problem.
Thanks for consulting us, have a nice day.
