Hello.
Hello, how may I help you?
I want to change my reservation, because I have some another important work on those dates, can you please change my reservation?
Sure, may I know your name please to check the reservation status?
Sure, my name is Jonathan Harris.
There is no reservation found with your details, Harris.
Oh! may be I am not booked my ticket properly at that time. Thank you for your information.
Thank you for choosing us.
