Hi.
Hello, how can I aid you?
As my plan to visit my grandmother's home got postponed, I need to change my existing reservation.
Ok, I can help you with changing your reservation. May I know your good name?
My name is Katherine Taylor.
Please wait. I will check the status and let you know.
Ok.
Thanks for your patience. There was no reservation found on your name.
Ok,  not an issue. Thanks for the information.
It's my pleasure to assist you. Have a good day.
