Hi.
Hello. How can I serve you?
I need to change my current reservation due to urgent meeting, can you help me with that?
Sure, I can help you.
Thank you.
May I know your name?
I am Thomas Walker.
Please wait a while I will check the reservation status.
Sure.
 Thank you for waiting, but I am sorry to say that, there is no active reservation found with your name in our database to change it.
That's ok, thank you.
Thank you for reaching us.
