Hi.
Hello, how may I serve you?
Lat week I have booked a ticket to Boston but due to heavy work load in my office, I want to alter my existing reservation. Can you please help me with that?
Sure, may I know your name?
Yes, my name is Daniel Miller.
Please wait a moment, I will check and revert you.
Sure, take your time.
Sorry there is no reservation found on your name.
That's ok, may be I have done a wrong booking. I will check it once and get back to you later.
Thank you for choosing us, have a good day.
