Hello, I am Dennis Jones.
Hello, how may I assist you?
As my plan to go for shopping got postponed, I want you to change my reservation. Can you please help me?
Sure. Let me check the reservation list and revert you.
Ok.
We have gone through the data base but could not find any reservation by the name you provided.
It's ok, no problem. Thank you for the information.
