Hello, I am Margaret Rodriguez.
Hello, How exactly I can serve you the best today?
As my manager did not approve my leave, I would like to cancel my recent reservation. Can you aid me with this?
Sure, I will help you with that.
Thank you.
Please wait a moment.
Sure, take your time.
Thank you for waiting.
Welcome.
 I have checked in reservation list to cancel your ticket, but could not find any reservation with your name.
That's ok, thank you for checking.
Thank you for choosing us.
