Hello.
Hello, How can I help you?
I am Michael Williams. I had planned to go on a trip, but it was postponed. Can you change my recent reservation?
Sure, I am perky to help you. Please wait for a while.
Ok, take your time.
Thanks  for waiting, we did not find any active reservation on your name in our records.
That's ok. Anyways, thank you for your help.
