Hello, how may I aid you today?
I have an earlier reservation to sign a new contract for new project, due to some problems it got postponed. Can you please help me in changing my reservation?
Sure, please share me your good  name.
Thank you for accepting my request, I have reserved it on the name of David Harris.
Please wait for a while.
Sure.
Sorry to say that, there is no active reservation found on your name.
