Hello. I am Jacob Jackson.
Hello Jacob, how may I help you today?
I had planned to go on a trip, but it was postponed due to some reasons. Can you change my recent reservation?
Sure, I am here to help you.
Ok.
Please wait for a mean while.
Sure.
Sorry Jacob, there is no reservation found as per your travelling details to change your reservation.
That's ok. Anyways, thank you for your help.
You are welcome.
