Hello, Karen Lewis here.
Hello Lewis, what can I do for you?
I postponed my holiday trip due to unplanned work in my office, so can you change my reservation?
Sure, I am happy to assist you with that.
So nice of you.
Can I put you on hold for a moment?
Sure, take your time.
Thank you for waiting. Sorry to tell you that, I didn't found any reservation with your name in the reservation chart list. Do you need anything else?
No problem, thank you for helping me.
You are welcome. Thank you for consulting our flight agency.
