Hi.
Hello, how can I oblige you today?
  Would it be possible to cancel my reservation, which I have done with my name?
Sure, can I know your good name?
Yes, my name is Pamela Mitchell.
Please wait for a moment.
Sure, take your time.
Thank you for waiting, there is no active reservation found with the given name.
That's ok, thank you for the response.
Thank you.
