 USER: Hi.

ASSISTANT: Hello, how may I help you for this moment?

USER: Debra Edwards here. Due to strange climatic conditions, I want to postpone my trip to some other dates. Can you please modify my reservation?

ASSISTANT: Glad to meet you, Edwards. Please wait for a mean while.

USER: Sure, I'll wait.

ASSISTANT: Sorry Edwards, there is no reservation found as per your name to modify any reservation.

USER: Oh! May be something went wrong while I was doing my reservation. I will recheck it once and get back to you later. Thank you for your service anyways.

ASSISTANT: You are welcome.
