Hello.
Hello. How can I help you?
I want to change my reservation due to some problems I am unable to travel those dates, can you please change my reservation?
Can you please provide the name on which the reservation has been confirmed?
Sure, my name is Betty Johnson.
Sorry, there is no reservation found by the name that you had provided.
Oh! May be I am not booked my ticket properly at that time.
Thank you and have a nice day.
