Hi.
Hello, how can I help you?
I want to reschedule my recent reservation as my plan to visit Lincoln memorial in Washington got postponed. Can you change my reservation made on name Debra Garcia?
Sure, I am here to change your existing reservation. May I know your name  for searching the previous reservation? Please wait for a while.
Ok.
There is no reservation on your name in our records.
That's fine.
Thank you for approaching us.
