Hello.
Hello. How can I help you?
As my manager did not approve my leave, I would like to change my recent reservation. Can you aid me with this?
Sure, I will help you to change your reservation.
Thank you.
Ok, please share me your name.
Myself Jerry Perez.
Sorry, no reservation found on your name to change your reservation.
That's ok, thank you for checking.
Welcome, have a nice day.
