Hi.
Hello.
I am Jason Perez.
In which way I can aid you at this moment?
 I made my reservation in advance, but now found out I don't have any leaves so want to cancel my reservation.Please help me to cancel it.
Sure, I will aid you with that. Please wait a moment, I will check your previous reservation status.
Ok.
There is no previous reservation available under your name.
That's Fine. Thank you.
