Hello,.
Hello, how can I assist you?
As my friend booked my ticket previously with wrong source code. So, I want to change my existing reservation. Can you help me out in changing my reservation?
Sure, Can I have your name please?
I am Mary Wright.
Please give me a minute, I will check with the current status of your reservation and let you know.
Sure.
Thanks for waiting, there is no reservation found with your name.
Ok. Thank you for rechecking my reservation.
Have a nice day.
