Hello.
Hello, how may I assist you now?
I am planning to change an existing reservation, due to health issue. Can you please change my reservation?
Ok, please share your name to check with your existing reservation.
Thank you, I am Edwards Johnson.
Give me a moment to check with availability of your reservation.
Sure.
Edwards Johnson, there is no active reservation by your name in our database. Sorry to the inconvenience.
That's fine, thank you for your service.
Have a nice day.
