Hello, I am Rachel Martin.
Hello, how  may I help you?
As my manager did not approve my leave, I would like to cancel my recent reservation.
Sure, can I have your journey dates?
I don't remember the exact date on which the ticket has booked.
Ok, Please wait for a moment.
Sure, take your time.
Sorry, there is no reservation found on your name.
That's ok, thank you for checking.
You are welcome. Thank you for reaching us, have a nice day.
