Hi, Joseph Moore here.
Hello. How may I assist you Moore?
I have booked a ticket for Houston, but I want to change my existing reservation to some other dates due to health issue. Can you please help me with that?
Sure, please wait a moment so that I can check it out whether your reservation is existed or not.
Fine, take your time.
Sorry, I could not able to find any ticket booked with your name.
Oh! I think it might have changed by my assistant. Thank you for your service.
Thank you for reaching us.
