Hello.
Hello. How can I assist you today?
 I need to cancel my reservation, as my friends have already booked my ticket in another flight along with theirs, I was not aware of this thing, can you please cancel that reservation for me?
Sure, I can help you with that.
Ok.
Please allow me a moment to check the previous reservation. May I know your name please?
Sure, take your own time. I am Kenneth Thomas.
Kenneth, I see that there is no reservation found under your name.
It's not a problem. Thanks for checking and giving information.
You are welcome. Thank you for contacting us.
