Hello.
Hello. How can I help you?
I want to change my reservation, due to some health problems I am unable to travel those dates, can you please change my reservation?
Sure, I will help you. May I know your name please?
Thanks. Sure, my name is Kevin Smith.
There is no reservation on your name in our database.
Oh! May be I am not booked my ticket properly at that time.
Thank you for opting us.
