Hello.
Hello, how may I render you today?
I made a reservation earlier to attend an interview. It has been completed in Skype. Can you please cancel my recent reservation?
Sure, I am perky to help you. May I know on which name the ticket has been reserved?
My name is Deborah Clark.
Please wait for some time, I will check with your  reservation status and revert to you.
Sure.
Thank you for waiting, we are sorry to inform you that, we did not find any reservation against your name.
That's Ok. Thanks for your quick response.
Thank you for approaching us. Have a nice day.
