Hi.
Hello, how can I help you today?
As my plan to visit my grand mother's home got postponed. So, can you please help me out in changing my existing reservation?
Sure, I am mirthful to help you with that.  Can you please share me your name?
Sure, my name is Carol Evans.
Please hold on for a while.
Ok, take your time.
Sorry, I didn't find any reservation on your name in our database.
That's ok, thank you for the response.
Thank you for reaching us, have a nice day.
