Hello, I am Richard Jones.
Hello, how can I help you today?
As my manager did not approve my leave, I would like to change my recent reservation. Can you aid me with this?
Sure, I am glad to help you with that.
Thank you.
Can you please tell me your name?
As I already said myself Richard Jones.
sorry, no reservation found on your name to change your reservation.
That's ok, thank you for checking.
