Hi, I am Brian King.
Hello. How may I serve you today?
Owing to an emergency, my meeting with project manager got postponed. So I want you to change my existing reservation.
Sure, I'll help you in changing an existing reservation. Please wait a moment I will check the reservation status.
Sure. OK, not an issue.
Thanks for waiting, there is no reservation found by your name.
Ok, no worries at all.
Thank you for choosing us.
